1.5 hp (1.12 kW) Pump Models Maximum working pressure • Choice of wetted materials • Single air head • Drive pressure 3 to 150 psi (.2 to 10 bar) Key Features • Choice of 11 models, 14 ratios, 50 possible combinations • Output pressures to 50000 psi (3448 bar) • Flows to 22 gpm (83.0 l/min) Nominal Ratio Consult chart on page 6 for more information regarding continuous/intermittent pressures. (1) These series are “Lift” pumps and maximum outlet pressure is (air drive x pump ratio) + inlet pressure (2) DTV has poppet checks For service codes, see page 17. For weights and dimensions, see page 20. Optional Modifications Number Air controls (filter, regulator, gauge, shut-off). ½” NPT. Double distance piece.
