Product Overview
The PMPSP/PMPSPL Sump Drainer uses the same internal mechanism as the standard PMP models. The piping configuration is such that the liquid is discharged vertically out the top as opposed to horizontally out the side. This allows the unit to be easily positioned inside of a sump area. Condensate or water from the sump enters the tank through a stainless steel low resistance check valve. This unit is capable of operating with a maximum motive pressure of 150 PSIG using steam, air, nitrogen or other pressurized gas as the motive force.
• Equipped with our Patented “Snap-Assure” Mechanism which extends the useful life of the pump
• Mechanism incorporates heat-treated stainless steel wear items for ultimate corrosion resistance
• Dual compression springs made from Inconel-X-750 for high-temperature corrosive service
• Operates using steam, air, nitrogen or other pressurized gas as the motive force
Non-Electric – can be used in remote locations or NEMA 4, 7, 9 and hazardous areas
• Built-in Strainer screen
Selection / Sizing / Capacities
Water enters the inlet check valve thru a screened area at bottom of pump. After the pump fills, the internal mechanism is actuated and the pump is discharged by the motive steam or compressed air. Other compressed gases such as nitrogen can also be used.
