 Impeller
Design
C Series semi-open impellers allow the pump to pass small solids
and fibrous material while close running tolerances maintain efficiency
and performance. Impellers are pre-trimmed to be non-overloading
to the pump and motor size indicated.
NPSH Requirements
C Series centrifugal pumps meet low net positive suction head
requirements (NPSHR) without sacrificing efficiency. This is achieved
by low fluid inlet velocity and gentle acceleration to peripheral
velocities.
Mechanical Seal Box
The large seal chamber provides a wide fluid passage area for
maximum cooling of the seal faces and allows debris and gases
to be flushed away.
Axial Balance System
The C Series pumps utilize a thrust balancing system which combines
the advantages of both static and dynamic balancing techniques
to reduce axial thrust and provide longer bearing life.
D3 Motors
Similar to the T31 Series, the C Series takes advantage of our
custom manufactured dual face D3 motors that incorporate a 304
stainless steel shaft and heavy-duty bearing. The stainless steel
shaft eliminates the necessity of a shaft sleeve, thereby reducing
the parts count and simplifying maintenance and servicing procedures.
All D3 motors also feature a two-pole 50/60Hz rating, as well
as CE Mark approval useful for OEM’s with worldwide customers.
The three-phase versions of the D3 motors feature a compact TEFC
enclosure and a range from 1/3 to 3HP. The single phase D3 motors
have an ODP enclosure and a range from 1/3 to 2HP.
Adjustable Casing
C Series pump casings are axially adjustable allowing the use
of custom impellers for OEM applications and to allow restoration
of performance by closing up the internal clearances that develop
over the course of a unit’s extended service life.
