Reliable Operation
Three barriers provide triple protection against motor-damaging water.
Two epoxy barriers and a compression fitting keep water out of the motor so you get long-term, reliable operation. A water-tight seal at cable entry is ensured with a single trumpet shaped elastomer grommet flanked by a washer and compression gland.

The top epoxy barrier keeps water out of the connection box and the lower barrier keeps moisture out of the motor area when the cord is disconnected. Leads going through both epoxy barriers are stripped down to bare wire at staggered intervals and each lead is individually separated. This lead-encasing design prohibits any wicking or capillary water movement inside the cord.

Low Maintenance
Hydromatic non-clog pumps are virtually maintenance free because the oil-filled design keeps the motor and bearings both fully lubricated and operating in the proper temperature range for very long life. You schedule and perform periodic maintenance for bearings and seals less often than required by other manufacturers.

Easy-To-Service
The volute-mounted wear ring is easily replaceable. It is made of bronze to give you long impeller life. HYDROMATIC pumps use a true wear ring, not a media lubricated bushing used by some manufacturers.

The top pullout design makes it easy to disassemble the pump in one operation in order to replace worn components, including the impeller. This reduces repair time and downtime. The tapered shaft available on models S4M and larger allows the impeller to be easily removed without special tools.

Stators are easily field replaceable with standard tools. Stators are reliably held in place with keys and a clamp ring. Some manufacturers with press fit stators require complete shop facilities for replacement.
The easily replaceable stainless steel shaft sleeve protects the shaft from corrosion and helps prevent shaft replacement.
