Installation Notes |
Pressure Regulator |
|
Used to accurately set and maintain consistent system pressure. |
Plumbed to the high pressure side of the pump manifold, preferably on a discharge port. |
Pressure Regulating Unloader |
|
Used to accurately set and maintain system pressure as well as reduce load on the pump and motor when the system is in by-pass. |
Plumbed to the high pressure side of the pump manifold, preferably on a discharge port. Must be in line with the discharge hose. |
Relief/Pop-Off Valve |
|
Provides your system with an accurate and reliable secondary pressure relief to protect your pump and system from damage caused by over-pressurization. |
Plumbed to the high pressure side of pump manifold before primary regulating device or on an open discharge port. Set 200-300 psi above system operating pressure. |
Pressure Gauge |
|
Used to accurately monitor pump pressure. |
Plumbed to the high pressure discharge side of pump. If mounted before an unloader and there flow is stopped downstream, the pressure will be near zero. If located after the unloader the pressure will remain at the set pressure. |
Pulsation Dampener |
|
Used to help provide smooth and consistent flow as well as increase overall system life.
Reduces pulsation to 1-3%. |
Plumbed on the high pressure side of the pump and as close to the pump as possible for optimum dampening.
If system uses an unloader where bypass flow is diverted back to pump inlet with a check valve or inlet regulator, the pulsation dampener must be plumbed after the unloader. |
Inlet Filter |
|
Used to capture and prevent contamination particles from entering and possibly causing damage to the pump and system components. |
Plumbed on the inlet side of a pump near the supply tank or before the any other inlet accessories. |
Thermal Valve |
|
Used to relieve heat build-up in closed loop by-pass systems. |
Plumbed in the bypass line near the inlet port for optimum performance. |
Oil Gauge/Drain Kit |
|
Used to provide convenient monitoring of crankcase oil as well as fast and convenient oil changes. |
Plumbed to the oil drain port located on the rear cover of the crankcase. |
Quick Start Valve |
|
Relieves discharge line pressure during system start-up when using pressure lock style unloader with gas/diesel engines. |
Plumbed in the high pressure side of the pump. When being used with an unloader, valve must be plumbed to discharge after unloader. |
Throttle Controller |
|
Reduces engine wear and fuel consumption by lowering rpm while running in bypass. |
Plumbed in the high pressure side of the pump. When being used with an unloader, valve must be plumbed to discharge after unloader. |
Low Pressure Seal (LPS) Monitor |
|
Alerts you when the low pressure seals are worn and need replacement with indication light or can be integrated via PLC. |
Replaces oil pan behind pump manifold. See product data sheet for selection and installation guide. |
Captive Acceleration Tube (C.A.T.) |
|
Used to stabilize and maintain consistent inlet pressure when dealing with high temperatures, booster pump feed, long inlet lines or pressure spikes caused by regulating valves. |
Plumbed directly to the inlet port of a pump. |
Bypass Hose |
|
Used to route pump flow from unloader back to pump inlet when system is running in bypass. |
Plumbed from the bypass port of a regulator or unloader back to the pump inlet or supply tank.
If plumbed back to the inlet of a pump it should be before an inlet regulator. Always use a thermal valve to protect from heat buildup when system is running in bypass. |
Oil Cap Protector |
|
Helps minimize water leakage into crankcase. |
Mounted on crankcase oil fill cap. |
Pump Rails |
|
Used to mount pump assembly to base. |
Mounted to crankcase feet.
Ensure that base is on an even, level surface. |
