General Description CPP

The CPP-21 line is designed to meet the ANSI B 73.1 specification. They are

designed around a single, basic hydraulic and mechanical design concept

which ensures the optimum efficiencies across a wide spectrum of operating

conditions, unparallel application flexibility and superior interchangeability.

The CPP-21 line features 35sizes to meet service conditions

for a wide range of hydraulic

parameters including low flow

and high head parameters.

What is the CPP-L CPP-L

The CPP-L is the low flow option

of the CPP-21 product line.

It is designed to fill the gap on thelow flow side of the CPP-21 range

map while utilizing the

mechanical seals from the CPP-21

The bearing bracket is designed

to adjust the axial lift.

Complies with the ANSI B 73.1

Standard.

Design Features & Benefits CPP-L

1. Low flow radial vane impeller

2. Circular concentric casing

Uses same size of Mechanical

Seal as CPP-21

These features reduce excessive radial loads and minimize

shaft deflection and thus prolonging bearing and seal life
