Finding the Best Hydraulic Pump for You
If you don’t know what pump fits your needs, call us and let us help you find the perfect tool for your job. Below is some information about the different uses for hydraulic pumps.
Mac’s Hydraulic manual pump line features high pressure hydraulic hand and foot pumps designed for portability, durability and ease-of-use. A large selection of hydraulic hand pumps makes it easy to find the most effective compact high pressure pump. The manual hand and foot pump line is also equipped with the numerous safety features provide dependable performance, while maintaining worker safety.
Hand Pumps: Hydraulic hand pumps play an essential role in every industry that requires the testing and calibrating of pressure instruments such as pressure transmitters, gauges, and switches. From energy production and health care to construction and wastewater management, they perform a very necessary function that ultimately helps keep our global economy running safely and efficiently.
Hydraulic hand pumps have come a long way since their humble beginnings. Today, there are a variety of styles and pressure ranges available, and they are all generally engineered to be rugged, lightweight and easy to use. But there are a few essential characteristics of the hydraulic hand pump that are worth highlighting, particularly in comparison to their pneumatic equivalents.
Efficiency – Hydraulic pressure is one of the most efficient methods of transferring energy. A hydraulic hand pump allows you to reach high levels of pressure with very little effort – just one or two squeezes of the handle. Because air is compressible, it would take a much higher degree of effort to reach the same levels of pressure with a pneumatic pump.
Precision – Hand-operated hydraulic pumps are ideal in situations where a high degree of fine-tuning is required. They’re typically engineered with fine adjustment knobs that allow the operator to vary applied pressure to within .01 psi or .069 kPa.
Stability – Hydraulic hand pumps are typically made with either cast or machined metal to limit leaks, prevent maintenance and ensure temperature and pressure stability.
Foot Pumps: Air Compressor Hydraulic foot pumps are really control valves which convert a 100 psi shop air source to, about, 10,000 psi hydraulic pressure for operating portable rams (generally used in body shops). The treadles are foot operated and provide reliable hands-free control of any kind of hydraulic driven equipment.
Electric Pumps: The use of variable-speed electric drives to power hydraulic pumps has grown with the development of high-speed controls, quick-response motors, and improved software that give these motor-pump combinations the power and responsiveness to match systems controlled by electrohydraulic valves or a variable-displacement pump, while also reducing energy consumption.
A hydraulic system with a variable-speed drive combines the robust, power-dense benefits of hydraulics with the intelligence and ease of integration into automation systems provided by electric drives. Energy efficiency is increased because pump speed is easily adjusted to flow demands, and the motor isn’t running constantly at high speed, regardless of load. Noise is also reduced, especially during operations where pump flow demand is below maximum. Varying the pump speed varies the flow and therefore matches the hydraulic power delivered to the exact amount needed at any point in a machine’s duty cycle, whether during operation, in standby, or while maintaining pressure. In addition, because these systems generally require less oil and consequently a smaller reservoir, the machine footprint can be reduced.
The benefits of variable-speed pump drives are paying off in applications that include machining and metal forming equipment, plastics and rubber machinery, die casting machines, pulp and paper machinery, hydraulic test stands, material handling equipment, and many other industrial applications.
Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement (flow through the pump per rotation of the pump) cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted. Hydrodynamic pumps are more frequent in day-to-day life. Hydrostatic pumps of various types all work on the principle of Pascal’s law.
Finding the Best Hydraulic Torque Wrench for You
If you don’t know what torque wrench fits your needs, call us and let us help you find the perfect tool for your job. Below is some information about the different uses for a hydraulic torque wrench.
Hydraulic torque wrenches are one of the most useful tools available for industrial applications. People who work at mining, refining and petrochemical jobs know how difficult it is to find the right tool for the job. And when it comes to bolting tools for tight spaces, there is nothing better than a hydraulic torque wrench. A hydraulic torque wrench is a power tool designed to exert torque on a fastener to achieve proper tightening or loosening of a connection through the use of hydraulics. A torque wrench is applied to the nut either directly or in conjunction with an impact socket. Hydraulic torque wrenches apply a predetermined, controlled amount of torque to a properly lubricated fastener.
Today’s tools offer benefits such as lighter weights, smaller nose radius dimensions for fitting into tight spaces, use of exotic alloys, actuation triggers on the tool itself, multi-position reaction members, 360° × 360° hose swivels, and the ability to run multiple tools simultaneously from a single power pack.
There are two types of hydraulic torque wrenches: square drive and low profile. Depending on the application, one or the other will be the best tool to use. A Low Profile Wrench is perfect for the tightest of spaces where it’s difficult to reach the fastener.
The main characteristics of a hydraulic torque wrench which set it apart from other powered wrenches of similar function are that:
it must generate torque using only hydraulic means
it must be self-ratcheting, and
it must include an accurate method of determining the amount of torque applied
Hydraulic torque wrenches typically offer accuracy of ±3% and have a high degree of repeatability making them well suited to applications where large bolts are involved and a high degree of accuracy is required.
A hydraulic torque wrench is significantly quieter, lighter weight and more accurate than pneumatic impact wrenches capable of similar torque output, making it an appealing alternative for many users to the very loud and cumbersome impact wrenches or torque multipliers which were formerly the only viable option for working with very large nuts and bolts until the hydraulic torque wrench was introduced.
Best Hydraulic Cylinder for You
A variety of hydraulic cylinder designs are available through Mac’s Hydraulic Tools.
If you don’t know what Hydraulic Cylinder fits your needs, call us and let us help you find the perfect tool for your job. Below is some information about the different uses for hydraulic cylinders.
Differences in design and manufacturing of cylinders depends primarily what the industry and application is. Each type uses a different methodology on how the end caps are attached to the cylinder barrel as well as internal nuances. Barrel and end cap wall thickness also varies depending on materials used, cylinder construction and operating pressures. The three most popular types of construction are tie-rod, welded rod and telescopic. All these types can be either single or double acting.
Tie rod style hydraulic cylinders use high strength threaded steel rods to hold the two end caps to the cylinder barrel. They are most often seen in industrial factory applications. Small bore cylinders usually have 4 tie rods, and large bore cylinders may require as many as 16 or 20 tie rods in order to retain the end caps under the tremendous forces produced. Tie rod style cylinders can be completely disassembled for service and repair, and they are not always customizable. The National Fluid Power Association (NFPA) has standardized the dimensions of hydraulic tie rod cylinders. This enables cylinders from different manufacturers to interchange within the same mountings.
Welded body cylinders have no tie rods. The barrel is welded directly to the end caps. The ports are welded to the barrel. The front rod gland is usually threaded into or bolted to the cylinder barrel. That allows the piston rod assembly and the rod seals to be removed for service. Welded cylinders have a narrower body and often a shorter overall length enabling them to fit better into the tight confines of machinery. Welded cylinders do not suffer from failure due to tie rod stretch at high pressures and long strokes. The welded design also lends itself to customization. Special features are easily added to the cylinder body, including special ports, custom mounts, valve manifolds, and so on. Welded body hydraulic cylinders dominate the mobile hydraulic equipment market such as construction equipment (excavators, bulldozers, and road graders) and material handling equipment (forklift trucks, telehandlers, and lift-gates). They are also used by heavy industry in cranes, oil rigs, and large off-road vehicles for above-ground mining operations.
Telescopic cylinders typically used when a stroke length is required which is considerably longer than the retracted length. They are designed with a series of steel tubes, called stages, each progressively smaller in diameter and nested within each other.
Double-acting cylinders use hydraulic or pneumatic pressure to both extend and retract the rod or sleeve. Double acting cylinders are more common than single acting cylinders.
Single-acting cylinders use hydraulic or pneumatic pressure to either extend or retract a single piston rod or sleeve from a cylinder. Generally, gravity or another external force returns the piston rod or sleeve to its no-pressurized state.
Best Hydraulic Jacks for You
If you don’t know what Hydraulic Jack fits your needs, call us and let us help you find the perfect tool for your job. Below is some information about the different uses for hydraulic jacks.
Hydraulic jacks are devices used to uplift heavy loads by applying force through a hydraulic cylinder. There are two types of hydraulic jacks: trolley hydraulic jacks and bottle hydraulic jacks. Both jacks perform the same function but have a difference in their functioning and making.
The hydraulic trolley jacks are considered to be very safe. The wheels of a trolley jack (or floor jack) make slight movements to make up for the shift in the car during weight distribution. Bottle jacks are suitable for personal use. They are compact and can easily carry in cars. Trolley jacks are better for professionals and car enthusiasts. Bottle jacks have a coin-shaped lift surface.
Trolley jacks are very common and a bit more expensive, but if well-cared for, it can last a very long period. When comparing trolley jack vs. bottle jack, trolley jacks are quicker and easier to use.
Comfort Level: Bottle jacks will not fit under cars that have a low clearance while trolley jacks will comfortably fit.
Base Compression: Trolley jacks are also more stable since they have a longer base and ability to distribute the weight of the lifted object across the base. Trolley jacks have wheels hence moves with the car while bottle jacks have no wheels hence do not move.
The better hydraulic jack, therefore, depends on you! At Mac’s Hydraulic our goal is to make sure that we help provide you with the perfect tool for your needs and comfort level.
