Large capacity, High head

Single-suction, single-stage Mixed-Flow Volute Pump with large capacity and high efficiency, capable of operating near maximum limits.

Handles a variety of liquid properties

Pump structure allows for selection of suitable parts depending on the type of liquid, such as chemicals or gypsum slurry, that comes into contact with them.

Metallic parts

All parts that come into contact with liquid are metallic and unexpected problems that result from parts such as rubber linings are avoided.

Reduction of maintenance costs

Inspection from the coupling side with back-pullout disassembly greatly reduces costs and frequency of maintenance. (Not available with YM-2510 and YM-3020)

Large selection of materials

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

Enhanced self-priming is also possible (Optional)

By interlocking the unique vacuum pump with a water-air separating mechanism (PAT.), self-priming even with suction piping across an embankment is possible, which enables automatic pumping operation. (YM-2512, YM-3022 and YM-3520)
