Showa YMAS Piston Pump

The YMAS is the workhorse of the automatic cyclic pumps. Its Heavy-Duty pump, 10 Watt Motor and aluminum reservoir (2.0 Lliters) makes it especially usable in tough production environments. Features include a wide opening for easy filling, sight gauge for level indication, a drop in filter for easy maintenance, and a drain plug to facilitate cleaning or changing lubricates. A float switch and larger reservoirs are optional.

If you are looking for a pump with a smaller reservoir, try the Showa SSMA. The Showa YMB, Showa SMD and Showa SMA are other alternatives.

Notice: Suction Filter should be replaced every 6 months or less.

Filter Part Number (30mm): F/1001

Filter Part Number (38mm): F/1201

An optional Low Level Switch is available for all models.
