VMS/VCMS Series Vertical Centrifugal Pumps

VMS Pumps

For Low Capacity, High Speed

VMS series pumps are vertical double case pumps. A back-to-back configuration of stages guarantees constant axial balance without balancing drums. Designed for low capacity, high pressure, and high speed operation, VMS pumps offer mechanical simplicity, safety and high efficiency.

Features & Benefits

VCMS series pumps are single or multistage centrifugal units designed for service with low to medium pressure and temperature conditions. They are also suitable for medium head service with limited NPSH. The design allows installation of as many as 24 stages that can reach the highest pressures (over 1,200 m of total differential head).

VCMS pumps can be used successfully for hot and cold refinery service, boiler feed service, log debarking, oil well re-pressurizing and pipeline service. Applications include refinery processes (downstream) and condensate extraction (power generation).
