The definition of pump shut-in pressure is the amount of pressure that is generated by the pump when it is at zero flow, or not flowing. This can also be called "dead head pressure."

What is stroke length of a pump?
The stroke length of a pump is the distance it travels up before it travels down. The distance traveling up takes in air or water depending on the type of pump. The down pressure expels the air or water.
Does the Viscosity changes with the temp and pressure?
The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.
Why is the suction line of a pump larger than the discharge line?
It is common practice to specify the pump suction line one size larger than the pump discharge line in order to increase the Net Positive Suction Head available (NPSHA) to the pump. A smaller suction line the same pipe size as the discharge line would result in more pressure drop in the suction line and reduce the amount of head available to the suction side of the pump. This in turn would result in an operating point closer to cavitation of the pump.
With a centrifugal pump what will a blockage in the discharge or suction side do to the pump amps?
A blockage in the downstream side of the pump could make this pump work harder raising the amps as the pump now has to do more work to get through the line. An upstream blockage would make the pump spin more freely lowering the amps on the pump as it will not be doing any work.
What should Petroleum and hazardous liquid pipeline structures include?
Pump Stations
What is the best definition of margin pressure in hydraulics?
Margin pressure is a term used in Closed Center, Load Sense type systems in hydraulics. The term refers to the pressure difference between the pump outlet(valve inlet) and the valve tank pressure). The margin pressure is the way the valve signal to the pump it's status.

What is the Oil pump pressure?
the pressure of oil that the oil pump is pulling?
What does a pump pressure sensor do?
The fuel pump pressure sensor monitors the fuel pressure of the vehicle.
What does a fuel pump pressure sensor do?
The fuel pump pressure sensor monitors the fuel pressure of the vehicle.
Where is the pressure switch in a well water supply?
The pressure switch is usually on the pump if it's a jet pump, or at the base of the pressure tank if a submersible pump.
What is a pressure compensated hydraulic pump?
it is a pump that delivers the same pressure irregardless of load
How do you use a water pressure pump?
There are many different ways to use a 'water pressure pump' . Any water pump will build up pressure, this is the basic principle of well pumps, and similar. Most are 'used' by a pressure switch which turns the pump on when pressure decreases to a certain point.
Is there a in tank fuel pump on a 1989 Ford F-150 van with duel tanks?
There is a low pressure fuel pump in each fuel tank. The low pressure pump feeds the inline high pressure pump. Newer models , I believe 1990 and up, changed to the high pressure in tank fuel pump and eliminated the in line pump.
What does a high pressure fuel pump do?
It pumps fuel at a higher pressure than a standard fuel pump.

Where is highest pressure in hydraulic pump?
At the pressure regulator.
