CLOSE COUPLE MONOBLOCK PUMP: XE-CCMP-0010 - Xenon Engineering Company

Close Couple Monoblock Pump XE-CCMP0010

A close coupled centrifugal pump is identifiable by having a single, continuous shaft between the motor and pump, rather than 2 shafts coupled. Due to the compact design of a close coupled pump, you won’t easily see the shaft. The pump casing is typically bolted to the drive end of the motor instead of being installed on a pump bearing frame. With only a single shaft, a close coupled pump often has many benefits over a traditional frame mounted pump.

These pumps are used throughout the world. Popular manufacturers and models of close-coupled pumps include XENON Pump model XE: CCMP-0010 a. Close-coupled pumps are called monoblock pumps in some European countries.

Operational Features

Motor and pump share the same shaft (monoblock, compact design).
No coupling alignment needed (reduces maintenance).
Bearings are within the motor, so pump side needs minimal servicing.
Used in continuous duty cycles (24/7 operation possible if sized correctly).
Often fitted with mechanical seals for shaft sealing.
