The Chem-Tech Series 200 and 250 are mechanically activated, heavy duty diaphragm feed pumps that provide excellent efficiency under strenuous conditions. The Series 200 pumps are popular for their rugged design for continuous duty operation, while the Series 250 combines the power and repeatability of piston pumps with the chemical resistance of diaphragm pumps for high pressure applications.
The Series 200 offers feed rates from 10 to 120 gpd (1.5 to 18.9 lph) and operating pressures up to 150 psi (10.3 bar), while the Series 250 offers feed rates to 108 gpd (17 lph) and operating pressures up to 225 psi (15.5 bar).
