Wall Mounted Hand Pumps

DEMA’s hand pumps are designed to pump 1 or 2 ounces (30 or 60 ml) of detergent, sanitizer, or other chemicals into a kitchen sink, bottle, machine, or any open container where chemical is mixed with water.

The 301 Series features a smaller profile on the wall and is available 1 ounce (30 ml) models only.  The 301 uses a stainless or Teflon check ball to maintain chemical prime and a stainless or Hastelloy spring.

The 302 Series feature a larger push area for greater activation and is available is 1 or 2 ounce (30 or 60 ml) models.  The 302 has higher chemical resistance as it uses polyethylene bellows, and chemical does not come in contact with a metal spring.
