Peerless C Series Pump

The Peerless Pump C Series Pumps are close coupled with standard C-face JM or JP solid shaft ball bearing motors specifi cally designed for pump applications in accordance with standards developed by the Hydraulic Institute (HI) and the National Electrical Manufacturers Association (NEMA).

Applications
Peerless Pump Series C close coupled single suction
pumps are designed for applications in medium duty
service and provide maximum pump value in heating, air
conditioning, booster and general circulating service.

Features
Series C Pumps are available in cast iron bronze fi tted
and all iron construction. Packed boxes or mechanical
seals are available. Pump casing is fitted with a bronze/steel replaceable wear ring. The pipe connection fl anges are equivalent 125# ANSI fl anges rated for 175# Maximum Working Pressure (MWP).
Motor bearings are grease lubricated and are sized for a
minimum of 20,000 hours L10 basic rating life or 100,000
hours median bearing life. Shaft is designed to limit the
shaft defl ection to no more than .002 at the seal faces.
The motor/impeller shaft is protected with a replaceable
(bronze/stainless steel) sleeve installed between the
shaft and the packing or mechanical seal.
Mechanical seals are designed for water service and
light hydrocarbons up to 2500F. Seals are face type with
Ni-resist seat, carbon washer, 18-8 stainless steel metal
parts and Viton elastomers.
Series C pumps are furnished with enclosed dynamically
balanced impellers for smooth, low vibration operation.
The impeller is keyed to the shaft for positive driving and
is secured in place with a stainless steel washer and
self-locking cap screw.
The impeller diameter is no more than 90 percent of
the maximum impeller diameter which the case tongue
or cut-water could accommodate. This design feature
results in low hydraulic noise levels.

Quality Engineering
Peerless Pump designs tough, versatile products to meet
your pumping needs. The C Series delivers variety,
durability, standardized options and configurations
unequalled in the industry.
