Dewatering pump features page 1

A: Junction Chamber: All Piranha P-Series dewatering pumps are equipped with a built in contactor wired to thermal protection embedded into the end coils of the stator. In the event of motor overheating the contactor is tripped and automatically resets when the motor cools. All electric cables enter through a sealing gland. Water sealing and strain relief functions are separated. The entire junction chamber is sealed off from the motor to prevent burn out should moisture enter due to damage to the cable.

B: Motor: A dry, shell type, squirrel-cage induction motor is standard on all Piranha submersibles. Stator windings are triple dipped class F insulation, rated at 310'F (155'C).

C: Bearings: Both upper and lower bearings are

pre-packed with special high temperature grease.

D: Shaft: Every Piranha pump is designed with a short shaft overhang. Shaft deflection due to hydraulic forces is virtually eliminated. The result is a dramatic increase in bearing and seal life. All Piranha shafts are made of stainless steel.

E: Seal: One of the most critical components of a submersible pump. Piranha pumps have unique lapped solid silicon carbide vs. silicon carbide seals. The Piranha bellows cartridge seal will withstand heat, corrosion, and abrasion no other seals could survive. This compact unit consists of a lower balanced cartridge seal and a upper spring loaded mechanical seal assembly. The seals are arranged in tandem, each operating independent of the other in an oil chamber. The oil acts as a lubricating and cooling medium for the seal faces.

F: Liquid End: Adjustable abrasion resistant stainless steel impeller and rubber lined diffuser permit optimum efficiency to be maintained despite wear. Rubber clad, easily replaceable wear parts.

G: Hose Connection: The discharge outlet can be placed in the straight out position or rotated 180' aiming the hose at an angle, eliminating kinks and bends, reducing friction losses.

H: O-rings: All mating components around motor are sealed with double o-ring seals.

I: Hardware: All Piranha fasteners and strainers are made of stainless steel.
