PMP & PUMP-TRAP APPLICATIONS REMOVAL OF WATER OR CONDENSATE FROM A PIT
PURPOSE:
For drainage of water and condensate from collection pits – especially with minimal horizontal space.
OPERATION:
Water enters the inlet check valve through a screened area at the bottom of the PMPSP Sump Drainer. After the pump fills, the internal mechanism is actuated and the water is discharged from the pump by motive steam or compressed air or other gas.
INSTALLATION GUIDELINES:
(see Figure 27)
• Make certain vent line is unobstructed and allowed to discharge directly to atmosphere. • Other compressed gases, such as nitrogen, may be used as a motive source. • Pit diameter should be at least 18” to ensure proper installation and operation. • Proper installation and piping of the pump vent line is critical to ensure the system operates correctly. Follow guidelines or consult factory for additional information. • Note that liquid level in the pit must rise above the pump to allow proper function.
