- Most positive displacement pumps cannot increase output pressure when placed in series as they both stop when they reach their max operating pressure.
- An oil diffusion pump is used to achieve higher vacuum ( lower pressure ) than is possible by use of positive displacement pumps alone.
- Some continuously variable transmissions use a hydrostatic drive consisting of a variable displacement pump and a hydraulic motor to transmit power without gears.
- Second the positive displacement pump backs up the momentum transfer pump by evacuating to low vacuum the accumulation of displaced molecules in the high vacuum pump.
- A positive displacement pump must not operate against a closed valve on the discharge side of the pump, because it has no shutoff head like centrifugal pumps.
- Since the lobes do not make contact, and clearances are not as close as in other Positive displacement pumps, this design handles low viscosity liquids with diminished performance.
- A liquid ring pump is a rotating positive displacement pump that is powered by an induction motor and is typically used as a vacuum pump or as a gas compressor.
- Positive displacement pumps, unlike centrifugal or roto-dynamic pumps, theoretically can produce the same flow at a given speed ( RPM ) no matter what the discharge pressure.
- Positive displacement pumps physically displace fluid, so closing a valve downstream of a positive displacement pump produces a continual pressure build up that can cause mechanical failure of pipeline or pump.
- Positive displacement pumps physically displace fluid, so closing a valve downstream of a positive displacement pump produces a continual pressure build up that can cause mechanical failure of pipeline or pump.
- The study of vacuum then lapsed until 1855, when Heinrich Geissler invented the mercury displacement pump and achieved a record vacuum of about 10 Pa ( 0.1 Torr ).
- Positive displacement pumps use a mechanism to repeatedly expand a cavity, allow gases to flow in from the chamber, seal off the cavity, and exhaust it to the atmosphere.
- :A pump that moves a set volume of fluid through the system for each revolution of the driving shaft . Positive displacement pumps are commonly used in conjunction with highsolids grouting materials.
- A positive displacement pump operating against a closed discharge valve continues to produce flow and the pressure in the discharge line increases until the line bursts, the pump is severely damaged, or both.
- Positive displacement pumps, however, tend to have sufficiently tight sealing between the moving parts and the casing or housing of the pump that they can be described as " self-priming ".
- One modern application of positive displacement pumps is compressed-air-powered double-bunds, to pumping hydrochloric acid from secure storage ( dependent on how the pump is manufactured elastomers / body construction ).
- A "'mud motor "'( or drilling motor ) is a progressive cavity positive displacement pump ( PCPD ) placed in the drill string to provide additional power to the bit while drilling.
- As with positive displacement pumps, the base pressure will be reached when leakage, outgassing, and backstreaming equal the pump speed, but now minimizing leakage and outgassing to a level comparable to backstreaming becomes much more difficult.
- In a typical pumpdown sequence, a positive displacement pump would be used to remove most of the gas from a chamber, starting from atmosphere ( 760 Torr, 101 kPa ) to 25 Torr ( 3 kPa ).
- Positive-displacement pumps deliver a nearly fixed volume of air per revolution at all speeds ( minus leakage, which is almost constant at all speeds for a given pressure, thus its importance decreases at higher speeds ).
