Water pump FD series

for chemicalsfor liquified gasair-driven

Key Features • Choice of 16 models, 13 ratios, 46 possible combinations • Output pressures to 100000 psi (7000 bar) • Flows to 5 gpm (15 l/min) • Choice of wetted materials • Double and triple air heads • Drive pressure 3 to 100 psi (.2 to 7 bar) When using high pressure ratio pumps the reliability of the XH models (-452 through -1373) will be improved with an air driven supercharge pump, not only to simplify priming but to reduce fatigue stresses. The higher the supercharge, the better the results. Also install a relief valve to protect the lower pressure pump from potential back pressure. Supercharging of the -1373 model is recommended. This approach will ensure a reasonable life for the seals and other wear components.
