•
The working pressure in the hydraulics system must be controlled by a pressure relief valve that is adjusted to
operate at 10% of the maximum system pressure.
•
When installing, adjusting or removing a Hypro centrifugal pump, ensure that there are no objects which can fall
on the installer and make certain that all machinery to which the pump is to be attached is turned off.
•
Pumps must be installed in a location where they are accessible for any necessary maintenance.
•
When hydraulic power is used, the system should contain a quick disconnect coupling that can be disconnected
to isolate the pump.
• 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.
• 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
• In order to prevent injury or damage to property, all Hypro pumps should be properly mounted to a solid base where
there is no danger of the pump falling or breaking loose. All Hypro pumps come with mounting holes which allow 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, pump inlet and outlet lines should be at least the same size as their
respective port, and should have as few restrictions as possible. Pump plumbing must be capable of withstanding the
maximum suction and pressure generated by the pump. Pump suction line must also be free of air leaks. Use good
quality suction hose that will not be collapsed by suction.
• For best priming results, the recommended orientation for the outlet port is pointing straight up. The upper most vent
plug can be removed and a vent line can be installed. This line prevents air lock and allows the pump to prime itself
by bleeding off trapped air. Avoid any dips or bends in the suction line plumbing that could trap air.
Hydraulic Installation
• Prior to installation, refer to the tractor or sprayer manual and determine what type of hydraulic system is being used.
The three types of systems include:
• Open center systems
• Closed center (Pressure-Compensated) systems
• Closed center Load Sensing (Flow and Pressure-Compensated) systems
• The hydraulic motor must be correctly configured and sized for the hydraulic system:
• Open center systems
• Excess oil from the hydraulic pump must be bypassed around the motor
• Built in bypass option in motor endplate, or separate bypass valve installed in the line feeding
the motor inlet.
• Use the largest motor possible
• Closed center (Pressure-Compensated) systems
• Metering orifices needed for optimal performance (see metering orifice section below).
• Use the smallest motor possible
