SESCO SES330 series inlet oil booster pumps are low pressure, low suction head, portable booster pumps designed to assist oil processors when circulating oil through a partially filled transformer being held under full vacuum. The SES330 is available in centrifugal and positive displacement pump versions.

The SES330S-2400 utilizes a special multistage suction centrifugal pump to supply up to 45 GPM with only 36" of oil suction head when the transformer is under full vacuum.  Many transformer processing specifications require hot oil circulation with a limited volume of oil before the dry out cycle. The SES330S enables the oil processor to circulate oil while under full vacuum with only 36" between the inlet of the pump and the oil level in the transformer. The SES330S is lighter, easier to store, and easier to position than it's larger heavier positive displace predecessors.

Mobile Low-Speed Positive Displacement Low NPSH Oil Processor Inlet Booster Pump. 

  • The Flow Rates Available 20,30, & 40 GPM. 
  • 7 PSI Maximum Discharge Pressure
  • 30" Oil Head Required Under Full Vacuum
  • Inlet & Discharge Shutoff Valves
  • Inlet and Discharge Compound gages
  • Discharge Flow sight
  • Locally Mounted NEMA 4X Starter Box

The traditional SES330PD positive displacement (PD) inlet booster pump is still available built to order.  The PD pump must be ordered to match the oil processor flow rate.  The low-speed PD pump requires slightly less oil suction head @ 40 GPM (30") and is less procedure sensitive to prime but has obvious weight, handling and storage disadvantages.
