Introduction Description Hypro centrifugal pumps are designed for agricultural and industrial spraying and transfer of a variety of fluids: water, insec- ticides, herbicides, wettable powders, emulsives, liquid fertilizers, etc. Hypro Series 9307 hydraulic motor-driven centrifugal pumps provide smooth performance. They can be conveniently mounted on the tractor or sprayer, becoming part of the vehicle’s hydraulic system and freeing the PTO for other uses.

Installation Instructions - cont’d. Check to see that the pump impeller can be turned by hand. (Turn the shaft clockwise using a deep socket wrench on the impeller nut.) If it cannot be turned, open the pump casing to look for obstructions. Clean out any corrosion build up where the casing fits over the eye of the impeller.
Installation Instructions - cont’d. Agitation The centrifugal pump control contains a manual agitation control valve that can be adjusted to provide the right amount of flow to the jet agitators in the tank to ensure proper mixing within the tank. Flowmeter To eliminate the mechanical problems of a turbine flowmeter, we recommend that an electromagnetic flowmeter be used.
Commissioning Start-Up, Operation, Shutdown Start-Up, Operation, and Shutdown Before Starting the Pump: Secure the outlet lines before starting the pump. An unsecured line may whip, causing personal injury and/or property damage. Check hose for weak or worn condition before each use. Make certain that all connections are tightly secured. The sound pressure level of the pump is 80 dBA.
Maintenance and Servicing Information When servicing your pump, you should adhere to the following safety guidelines: 1. Disconnect power supply before servicing. 2. Release all pressure within the system before servicing any component. Flush with water. 3. Always drain and flush pump before servicing or disassembling for any reason. 4.
