Model D04 Series (US) / G04 Series (Metric) -Diaphragm Pump

Versatile, Reliable Pumps for a Wide Range of Applications. Pumps the full spectrum of low-to-high viscosity fluids. Features a seal-less design and horizontal disk check valves that enable the pump to handle abrasives and particulates that might damage or destroy other types of pumps. Simple, compact design reduces initial investment and lowers maintenance costs. Operational efficiencies reduce energy costs. Able to run dry without damage (or additional maintenance) to the pump in case of accident or operator error. Tolerates non-ideal operating conditions. Minimizes maintenance and downtime because there are no seals, packing or cups to leak or replace.
