Hydraulic Installation
• Prior to installation, refer to the tractor or sprayer manual and determine what type of hydraulic system is being used.
Thethreetypesofsystemsinclude:
• Open center systems
• Closed center (Pressure-Compensated) systems
• Closed center Load Sensing (Flow and Pressure-Compensated) systems
•Thehydraulicmotormustbecorrectlyconguredandsizedforthehydraulicsystem:
• Open center systems
• Excess oil from the hydraulic pump must be bypassed around the motor
•Builtinbypassoptioninmotorendplate,orseparatebypassvalveinstalledinthe
line feeding the motor inlet.
• Use the largest motor possible
• If a rigid plumbing system is to be used on a Hypro centrifugal pump, the system must be properly aligned with
the inlet and outlet ports.
• For pumps with gas engines, the exhaust must be directed away from operators and anyone standing nearby to
ensure that exhaust fumes do not enter their breathing zone.

• Pumps must be installed in a location where they are accessible for any necessary maintenance.

to isolate the pump.
• When a main electrical supply is needed to power electric-drive motors, installers are responsible for ensuring that
a supply disconnect device, capable of isolating the machine from its electricity supply, be provided.
Standard Mounting

bolts to be put into the pump so it can be secured to a sturdy base. When mounting your Hypro centrifugal pump, be
sure to use bolts and nuts which are compatible with any chemicals that may come into contact with them as well as
choosing the correct grade of bolt based on the pump weight and any expected loads. Pumps should be mounted
as close to the liquid source as possible. Non self-priming pumps must be mounted below the liquid level to function
properly.
Pump Plumbing
• To achieve maximum pump performance, the outlet port on the pump should be pointing straight up, and pump
inlet and outlet lines should be at least the same size as their respective port. Pump plumbing must be capable of
withstanding the maximum suction, and pressure, generated by the pump and should have as few restrictions as
possible.
• For best priming results, the upper most vent plug can be removed and a vent line can be installed. This line prevents

plumbing that could trap air.
