>Selection & DimensionsMCF 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.
Boiler feed
Water supply to high elevations
Pressurized water discharge
Seawater transfer
