Cast Stainless Steel Pumps

Stainless Steel pumps are available in vertical and submersible floor mount models. All pump components are cast, not welded, 316 stainless steel.

Submersible Features

Case

Heavy duty, close grain, high density 316 stainless steel with tripod support legs.

Impeller

Statically and dynamically balanced 316 stainless steel.

Motor

NEMA-6, submersible, air filled, hermetically sealed, Class F insulation. Single-phase voltages are 115 or 208-230 with built-in auto reset thermal protection. Single-phase models include capacitors and relays mounted in a separate Type 4X FRP enclosure and are available up to 2 HP. Three-phase voltages are 208-230 or 460 and are available from 1/2 to 5 HP.

Shaft

316 stainless steel.

Motor Shell

316 stainless steel with special integral cooling fins.

Seal Chamber

316 stainless steel construction and filled with clean biodegradable oil for continuous mechanical seal lubrication.

End Bell

316 stainless steel, hermetically sealed.

Elastomers

Viton (fluorelastomer) rings for positive sealing are standard.

Power and Sensor Cable

All models have 25 feet of neoprene jacketed cable as standard.

Bearings

Permanently lubricated single row, double sealed. Oversized to handle radial and axial loads.

Seal – Tandem

Two seals. The upper seal operates inside the seal chamber. The upper seal face is carbon against ceramic. The lower seal faces are silicon carbide against silicon carbide.

Moisture Sensor

Designed to detect water in the seal chamber.

Temperature Limiter

Located in stator windings to stop motor when internal temperature exceed insulation rating. Automatic reset when motor cools.

Vertical Features

Case

Heavy duty, close grain, high density 316 stainless steel.

Impeller

Statically and dynamically balanced 316 stainless steel.

Motor

Vertical, solid shaft with NEMA-C mounting flange. Totally enclosed motors are standard on all models. The motor is connected to the pump with a flexible coupling.

Motor Horsepower

1150 RPM – 1/2 HP through 1-1/2 HP.

1750 RPM – 1/2 HP through 5 HP.

3450 RPM – 1-1/2 HP through 5 HP.

Shaft

316 stainless steel, polished and ground.

Thrust Bearing

Grease lubricated, ball type, over-sized for increased life and capacity. Sealed to protect from dirt and moisture.

Lower Bearing Housing

316 stainless steel with graphite sleeve bearing.

Intermediate Bearing Housing

316 stainless steel with graphite sleeve bearing.

Legs

316 stainless steel.

Discharge Pipe

316 stainless steel.
