The Plunger Pump functions like a piston pump, it sits within the oscillating positive displacement pump sector. However, instead of a piston, such pumps have one or several plungers as displacing element(s). The plunger is fed straight into a working chamber by a stroke movement, whereby the plunger is sealed off by a fixed seal. During intake, the plunger moves out of the working chamber, generating a suction effect, as the liquid to be conveyed streams into the pump through a suction valve. With the conveying movement, the plunger moves back, and the suction valve closes due to its own weight, a pressure valve opens, and the medium is conveyed out of the pump by the plunger.
The Grosvenor Plunger Pump Range delivers significant pressure through the utilization of high efficiency valves on the suction and discharge ports. This high pressure delivery results in an extremely accurate dosing solution.
Pump ends for the standard Plunger Pump are available with either 316 Stainless Steel or Cast Iron and Brass components. Valve assemblies are 316 Stainless Steel or Brass. The Valve Balls are available in 316 Stainless Steel, PTFE, Ceramic for Polypropylene. Valve Springs are 316 Stainless Steel and Gland Seals and O-Rings are Nitrile or PTFE. These pumps deliver up to 860 litres per hour at up to 175 bar pressure.
Grosvenor Plunger pumps can be used in a wide variety of applications, wherever liquid media has to be pumped at high pressure, they provide suitable solutions.
Given our sophisticated design, optimized material selection, flexible speed control and high precision manufacture, our plunger pumps can be used 24 hours a day without interruption. All material can be pumped in a liquid state. This can be water or oil at normal temperatures, but also hot oils and liquid gasses such as carbon dioxide and ammoniac. Due to their functional principle, plunger pumps are ideally suited for solutions with abrasives such as detergent slurries or coal mashes.
Typical Applications for Grosvenor Plunger Pumps Include:
- Process Technology for the Chemical and Pharmaceutical Industries
- Pressure Testing
- Urea Production
- Cleaning Applications
- Oil and Gas Production
- Coal Liquefaction
