Direct Drive Pump
Belt Driven Pump
Function
Used to accurately set and maintain system pressure and reduce the load on the pump and motor when the system is in bypass.
Installation Notes
Plumbed to the high-pressure side of the pump manifold, preferably on a discharge port. Must be in line with the discharge hose.
Function
Used to accurately monitor pump pressure.
Installation Notes
Plumbed to the high-pressure side of the pump manifold, preferably on a discharge port.
Function
Provides your system with an accurate and reliable secondary pressure relief to protect your pump and system from damage caused by over-pressurization.
Installation Notes
Plumbed to the high-pressure side of the pump manifold before the primary regulating device or on an open discharge port. Set 200-300 psi above system operating pressure.
Function
Chemical Injectors provide and regulate chemicals into the pump stream.
Installation Notes
Plumbed to the high-pressure side of the pump manifold, preferably on a discharge port. Must be in line with the discharge hose.
Function
Used to relieve heat build-up in closed-loop by-pass systems.
Installation Notes
Plumbed in the bypass line near the inlet port for optimum performance.
Function
Relieves discharge line pressure during system start-up when using pressure-sensitive regulating unloader with gas/diesel engines.
Installation Notes
Plumbed in the high-pressure side of the pump either downstream from an adjustable unloader valve, or an accessory discharge port.
Function
Reduces engine wear and fuel consumption by lowering rpm while running in bypass.
Installation Notes
Plumbed on the high-pressure side of the pump manifold.
Function
Used to ensure proper oil level in the crankcase.
Installation Notes
Ensure that the oil level is up to the midpoint of the dot on the oil gauge when on a level surface.
