Hydraulic Submersible Pump
hydraulic submersible pump

INTRODUCTION
Our hydraulically powered submersible dewatering and trash pumps have been engineered
to provide long lasting pumping performance with economic advantages that no other
pump can match. Yet, even a well-designed and well-built pump can malfunction or become
hazardous in the hands of an experienced or untrained user. Anyone that operates or comes
in contact with these products must thoroughly read and understand this manual and related
equipment manuals prior to handling, operating or servicing these pumps.
SAFETY RULES
1. Only use the pump in accordance with the manufacturer’s specifications and limitations.
2. Only trained personnel shall operate the pump, conduct maintenance or repairs. A trained
person has read and thoroughly understands this instruction manual and related equipment
manuals and, through training and experience, has shown knowledge regarding safe
operational procedures.
3. Always use appropriate personal protection equipment (PPE) including, but not limited
to: eye and ear protection, safety shoes, hard hat and work gloves.
4. Safety goggles must be worn at all times by the operator and any persons or bystanders
within 100 feet of the pump or its discharge point.
5. Never lift or lower the pump by its hydraulic hoses; use a cable and a lifting eye where
applicable.
6. Do not use any hose showing signs of damage or wear, including both hydraulic and
discharge hoses.
7. Secure the discharge hose before operating.
8. Do not allow the discharge hose to be kinked while in operation. If pumping in a shallow
basin use a 90 degree elbow on the pump to prevent kinking.
9. Keep all body parts clear from discharge hose and pump inlet. Keep all body parts
away from pressurized hydraulic hoses.
10. Always stop hydraulic power source and depressurize the hydraulic system before
connecting or disconnecting hydraulic hoses.
11. Never try to adjust or service the pump while connected to a hydraulic power source.
12. Hydraulic hoses must be rated for 2500 PSI working pressure and hydraulic power
source must not provide more than 2250 PSI at any time
BEFORE OPERATION
1. Anyone that operates or comes in contact with these products must thoroughly read
and understand this manual and related equipment manuals prior to handling, operating
or servicing these pumps.
2. Check hydraulic flow and relief pressure at the power source. Never exceed the pumps
maximum flow rate or pressure. The power source must be open center, single directional
and have an unrestricted flow from the pump back to the reservoir.
3. Inspect all hoses for breaks, cracks, abrasions, kinks, bulges or erosion from chemical
exposure before use. Replace damaged hoses before use. Inspect pump for damage
and insure all decals and warning labels are intact and legible.
