The PMPSP Sump Drainer (also known as "The Pit Boss") is a special PMP designed for pumping water out of low-lying areas or pits. Sump drainers are similar to the standard PMP models except that they discharge the condensate vertically upwards. This piping configuration allows them to easily fit into below ground sump pits with limited space.

Watson McDaniel Pump-Traps are available with either an internal steam trap or an external steam trap to suit individual application requirements:
The Model PMPT low-profile pressure motive pump has an internal steam trap for applications requiring compact design due to spatial constraints. It is an excellent choice for drainage of various modulating process equipment.
The WPT Series are stand-alone pump units with an appropriately sized external steam trap preassembled at the factory and mounted on a common base plate, allowing for easy installation. Pump-Trap combos with an external trap are suitable when capacity requirements exceed internal steam trap designs. These units are available in several sizes and capacities.
