Multistage Centrifugal Pump

Multistage Centrifugal Pump
MCF, MCH types

High head type with high performance and wide variety of materials

Multistage Centrifugal Pump

Bore

40-200mm

Total head

50-400m

Capacity

0.1-7m3/min

>Selection & Dimensions

MCF type (Driven by 2-pole motor):

Compact, high head, high performance multistage centrifugal pump
for force pumping

MCH type (Driven by 4-pole motor):

High head, high performance multistage centrifugal pump
for force pumping


Self-balancing mechanism

With the floating disk type balancing mechanism originally developed by YOKOTA for the MCF and MCH types, the axial thrust of its main shaft balances without axial movement of the shaft. Therefore ordinary ball bearings can be adopted, and the pump can be disassembled and reassembled very easily.

Large selection of materials

A wide variety of materials are available, including FC, SCS and YOKOTA's corrosion and wear resistant special stainless steel casting (YST), to meet the needs of various kinds of liquid.


Applications

Boiler feed

Water supply to high elevations

Pressurized water discharge

Seawater transfer

Other

Example applications and installations

Multistage Centrifugal Pump / Electric power plant funnel flushing pump
Multistage Self-Priming Pump / Water supply pump for Oita Safari Park
Water supply pump for Oita Safari Park
Electric power plant funnel flushing pump

These are non-self-priming type pumps for force pumping.
For self-priming types (for suction pumping) with similar specifications,
please refer to Multistage Self-Priming Pump USM, UBM, MEF types.
