• All maintenance should be done when machinery is stationary and has been isolated from its energy
sources. It is dangerous to perform maintenance while machinery is still connected to its power source. Machinery
should be isolated from its electrical, hydraulic, shaft driven, or gas engine power source.
• Be sure to release all pressure from the system before performing any sort of maintenance on a Hypro pump.

Replacement Parts
The following drawings show the pumps and their replacement parts.
Only genuine replacement parts should be used. Failure to follow this warning can result in damage to
property, serious injury or death. If the pump malfunctions or is defective, it should be sent back to Hypro for
service.
Preventative Maintenance Checklist
• DO NOT perform service or maintenance to the pump, or attached components, until the pump unit is
below 109°F (43°C).
• The lubrication of this pump unit has been done at the factory prior to shipping.
• When handling Hypro pumps, wear steel-toed shoes and protective gloves in order to protect your feet in the
event the pump is dropped and protect yours hands from chemicals or any sharp surfaces on the pump. If the
pump is being repaired while the pump is in service, eye protection should also be worn.
• Any hazardous liquids should be disposed of in a manner which complies with local and national regulations.
Never dump fluids onto the ground.
When disposing of a Hypro pump, be sure to remove all fluids from the pump before scrapping. These fluids should be
disposed of in a manner which complies with local and national regulations. Never dump fluids onto the ground. Once
the pump is free of all fluids, it must be scrapped in accordance with local and national laws.
Your pump will last longer and give best performance when properly taken care of. Proper pump care depends on the
liquid being pumped and when the pump will be used again. After each use, flush pump with a neutralizing solution for
the liquid just pumped. Follow with a clean water rinse. This is especially important for corrosive chemicals. It is good
practice to clean the pump after each use to prevent deposits from forming and damaging the pump. For infrequent
use and before long periods of storage, drain pump thoroughly. Open any drain plugs, remove suction hose from
liquid, and blow pump dry with air. An antifreeze/rust inhibitor should be injected into the pump before both ports are
plugged and the pump is stored. Plug all ports to keep out air until pump is used again.
• Each system’s maintenance cycle will be exclusive. If system performance decreases, check immediately.
• Duty cycle, temperature, quality and type of fluid being pumped, and inlet feed conditions all affect the life of
pump, motor components, and service cycle.
