Product Overview

FOUR POSITION CASING
Centerline discharge can be located in any of four
positions. Back pull-out design eliminates the need to
disturb piping should the pump ever require service – the
casing stays in the line.

Of the latest hydraulic design for maximum effi ciency,
impeller is balanced for vibration-free operation and
threaded onto stainless steel motor shaft.
MECHANICAL SHAFT SEAL
Standard self-adjusting shaft seal for temperatures to
225°F (107°C) and pressures to 150 psi (1034kpa).
Ceramic seat and carbon seal face for long troublefree
service. Special seals are available for higher
temperatures and fl uids other than water.
MOTORS
Standard pump motors have open drip proof construction
and are rated with jet pump service factors for continuous
duty operation. Motors are 56 frame size with NEMA
