HYDRASUB 20/25 HYDRAULICALLY DRIVEN SUBMERSIBLE PUMP

INSTALLATION, OPERATION, AND REPAIR MANUAL

HYDRASUB 20/25 is a compact, lightweight,

hydraulically driven submersible pump with high flow

capabilities. This self-priming pump is made with a

high strength aluminum alloy that is anodized for

corrosion resistance. This pump features a stainless

steel impeller, ball bearing, and a gerotor type

hydraulic motor. HYDRASUB 20/25 may be used to

pump out underground vaults and pits.

GENERAL SAFETY INFORMATION:

THE FOLLOWING WARNINGS ARE USED TO NOTIFY AND ADVISE THE USER OF THIS PRODUCT OF PROCEDURES

THAT MAY BE DANGEROUS TO THE USER OR RESULT IN DAMAGE TO THE PRODUCT.

THIS BULLETIN MUST BE READ COMPLETELY BEFORE INSTALLING, OPERATING, OR SERVICING, THE PUMP.

FORM 3069A (05-04)

WARNING

NEVER OPERATE THE PUMP WITH UNSECURED HOSES

AND HYDRAULIC LINES. SEVERE INJURY MAY OCCUR

FROM IMPACT, IMPINGEMENT, OR LIQUID BLAST.

COLD WEATHER OPERATION MAY REQUIRE

PREHEATING THE OIL OR BYPASSING THE OIL IN THE

POWER SUPPLY TO PREHEAT IT UNTIL THE OIL

REACHES A TEMPERATURE OF 50

• DO NOT perform service or maintenance

when the pumping system is pressurized.

• DO NOT continue to operate the pumping

system when a known leak exists.

• DO NOT operate beyond the pressure

or temperature limits stated in the product

literature. See Form 8107/8108.

• DO NOT operate the pump in a manner

that it was not intended to be used.

• DO NOT use in explosive atmospheres or

pump volatile liquids.

INSTALLATION:

HYDRAULIC OIL SYSTEM REQUIREMENTS:

The hydraulic power supply must be capable of delivering a

controlled flow rate of 5-9gpm for Model 20 and 8-14gpm for

Model 25. The operating oil pressure will vary upon the flow

rate load of the pump from 700 to 2100 psi. A maximum relief

valve setting of 2400psi is recommended.

A hydraulic supply system where the flow rate is controlled is

referred to as an “open center system.” This is the most

accurate system to assure that the flow rate does not exceed

the maximum limit.

A “closed center system” will have a variable oil flow rate based

upon the hydraulic pressure that is a set value. If a closed

center system is used, the maximum pressure developed must

not exceed 1700 psi, and the pump must always have a

supply of water to pump to protect it from running into an over

speed condition unless the oil flow rate is limited to less than

the maximum.

The maximum return pressure or backpressure is 100psi.

Higher pressures will result in reduced seal life. Do not install

down stream loads or valves. Always allow the return to go

directly back to the tank.

Supplemental oil cooling may be required to keep the oil

temperature below 175

F. Suitable filtration is required

(25 micron recommendation) to clean the oil of contaminants

that may accelerate wear.
