Displacement pumps manual

These pumps produce energy only when it is required. Also, these pumps reduce the use of flow control and pressure control valves. Piston pumps and Vane pumps are the two categories of variable displacement pumps. More details about these pumps are provided below. High efficiency, ease of operation at high pressure and various applicable control types are the advantages of piston pumps.

Pistons, the piston or cylinder block, valve plate, piston shoes, swash plate, and the drive shaft are the important components in a piston pump. Axial piston pumps, radial piston pumps and bent axis piston pumps are the common types of piston pumps.

The pumps that convert the rotary motion of an input shaft to axial reciprocative motion of the piston are called axial piston pumps.

In bent axis piston pumps, the axis of the cylinder block is bent for producing reciprocative action of the piston. For radial piston pumps, the pistons are aligned radially on the cylinder block. A vane pump contains a number of vanes slide in slots in a rotor and it can be converted to pressure compensated pump by replacing the hand wheel. Pressure compensated pumps mean, the pump operation ceases when the pump attains a certain pressure.

For each revolution, variable displacement vane pumps deliver the same volume of fluid. Direct operated and pilot operated are the two types of variable displacement vane pumps.

A neoprene diaphragm resists oil and chemicals such as isopropyl alcohol and deionized water. These pumps have a rugged aluminum housing for moving large volumes of thick sludges and slurries in demanding environments.

The Santoprene diaphragm resists cracking for a long service life and stands up to water and chemicals such as ammonium hydroxide. Also known as sprayer pumps, these provide a smooth, uniform flow for agricultural spraying, soap dispensing, and chemical transferring. Small enough to fit in the palm of your hand, these pumps transfer water, detergents, and chemicals.

Used to move liquids in food, beverage, dairy, and cosmetic lines, these pumps are powered by air and have a sanitary design certified by 3- A. Made of FDA listed materials for use with food and beverage, these pumps have a sanitary quick-clamp fluid connection for easy cleaning.

They are commonly used to move sauces, concentrates, and other thick liquids with solids. Absorb pulsation caused by air-powered transfer pumps, reducing wear and preventing damage to inline components such as regulators, sensors, and gauges.

With a stainless steel housing and a fluoroelastomer diaphragm, these pumps resist a variety of harsh acids and alkalies, such as phosphoric acid, nitric acid, and sulfuric acid. They have large internal pathways and check valves with flaps to accommodate thick sewage, abrasive slurries, and industrial waste with large solids that would damage standard air-powered transfer pumps.

A neoprene diaphragm stands up to oil and chemicals such as isopropyl alcohol and deionized water. These pumps have large internal pathways and check valves with flaps to accommodate thick sewage, abrasive slurries, and industrial waste with large solids that would damage standard air-powered transfer pumps. The fluoroelastomer diaphragm withstands higher temperatures than a neoprene diaphragm and has better resistance to fuel such as gasoline and kerosene. These pumps can be grounded to dissipate static electricity and are rated for use with flammable liquids such as gasoline, kerosene, isopropyl alcohol, and mineral spirits.

UL listed for pumping petroleum products and rated for use with flammable liquids, these pumps move diesel fuel, gasoline, kerosene, and mineral spirits. They can be grounded to dissipate static electricity. Commonly called piston pumps, these are often used in high-pressure applications, such as hydrostatic testing of pipelines, tanks, and valves.

Also known as peristaltic pumps and tubing pumps, these maintain a fixed flow rate. Install these pumps in a panel cutout. Often used in food and beverage, pharmaceutical, and lab applications, they dispense small amounts of liquid at a set rate. A stainless steel housing provides corrosion resistance for a long life in harsh environments. Commonly used in mining, wastewater treatment, and other systems that require large-diameter hose, these pumps have flanged hose connections and large diameter tubing.

With a footprint that's only a few inches in any direction, these pumps fit into compact systems to dispense small amounts of acids, cleaning fluids, and other chemicals. They're often used in sterilization, photochemical, and water treatment systems. Dispense precise amounts of fluid from a syringe.

Commonly used in chemical and pharmaceutical research, fiber production, and equipment calibration, these pumps maintain a steady flow rate for accurate filling and measuring. Rated for liquids with a viscosity up to 10, centipoise, these pumps can be used with very thick chemicals such as electropolishing solutions. An adjustment screw lets you increase or decrease flow rate without the hassle of changing tubing.

Often used in boiler feed systems and water treatment, these pumps are compatible with chemicals such as cleaning fluids and acid-washing solutions. These pumps can be used with pressures four times higher than standard pumps for chemicals. An adjustment dial with a locking lever allows for easy flow control.

Also known as diaphragm metering pumps, these can be used with pressures up to four times higher than standard pumps for chemicals. Inject chemicals into your water supply without using electricity— these pumps install directly in your pipeline and activate when water flows into the pump head. Automatically control output from a distance using variety of analog and digital signals, including mA and external pulse signals.

For high -volume chemical sampling and draining, these pumps have a powerful motor that enables them to move 2, gallons of liquid per day. Use these pumps for high-pressure output of antifreeze, hydraulic oil, and motor oil. Keep your metering pump in working order by replacing worn parts. This pump has a totally enclosed nonventilated TENV motor that is cooled by the liquid being pumped. Also known as a flexible impeller pump, it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump.

Convenient to keep in your toolkit for on-site cleanup, these pumps attach to your drill for small liquid extraction jobs as well as draining water from clogged sinks and emptying tanks. Install these pumps right in your line and engage the lever handle to start pumping. These pumps have a selectable flow rate, so you can adjust flow for different dispensing applications. A lever handle maximizes output with each stroke for low-effort dispensing. For low -effort dispensing, these pumps have a lever handle that maximizes output with each stroke.

Use them to pump lubricating oil, such as motor oil. Rotate the handle to dispense a continuous flow of liquid. For low -effort dispensing, a lever handle maximizes output with each stroke. The handle delivers fluid on both the forward and backward strokes to quickly move drum contents. A nozzle and hose allow you to dispense directly into your container. The lever handle maximizes output with each stroke for low-effort dispensing. Commonly used in food, beverage, pharmaceutical, and cosmetic processing, these pumps are designed for sanitary environments.

The polypropylene housing provides good resistance to caustics such as ammonia, electropolishing solutions, and detergents and cleaning fluids. A chemical - and impact-resistant PVDF housing stands up to aggressive chemicals such as methyl ethyl ketone and xylene. These pumps are designed for use in food and beverage applications.

A stainless steel construction allows these pumps to be used with aggressive chemicals such as methyl ethyl ketone and xylene. Pump fuel such as gasoline, kerosene, and diesel fuel. Generate a vacuum on demand with these pumps that come mounted on a gal. ASME code vacuum tank for quick startup. They're often used in vacuum-forming applications, such as product packaging. Use them for air and gas sampling, filtration, and refrigeration service. These pumps weigh only 16 pounds and have a handle, so they're convenient for on-site sampling, atomizing, and vacuum filtration.

Generate the suction you need to power end-of-arm tools, such as vacuum cups and grippers, without using an installed vacuum system. These pumps, also known as venturi devices, connect to any compressed air source and come with all the electrical connections you need to start lifting or moving objects.
