Hydrasub Submersible Pump

MP Pumps Submersible hydraulic driven pump. 34148 .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. HYDROSUB 20 / 25 may be used to pump out underground vaults and pits, golf course sand traps bunkers. High suction lift applications such as sewer bypass jobs. Dewatering of mines, quarries and gravel pits. Benefit: No suction line limitations. Unattended operation. Submerged pump head. Variable speed. No electrical requirements.
Trash type impeller also good for food waste streams. 34148
Can run dry. No priming required.
DO NOT use in explosive atmospheres or pump volatile liquids.

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 1750F. Suitable filtration is required (25 micron recommendation) to clean the oil of contaminants that may accelerate wear.
