Air-driven liquid pumps are available in three series: AHP03, AHP06, and AHP10. They can transport liquid media and gas-liquid mixtures (such as Freon). Air-driven gas boosters are available in two series: AGB06 and AGB10. They can compress and transport air, nitrogen, argon, CO2, and other high-purity gases. Manual pumps are available in two series: single-stage and two-stage pumps, with four pressure levels: 6000psi, 10000psi, 20000psi, and 30000psi, and optional configurations such as pressure relief valves and overflow valves. The electric piston pump is a 4-plunger inclined disc piston pump with a ball seat type one-way valve at the inlet and outlet. It has five flow rates to choose from and three pressure levels of 6000psi, 10000psi, and 15000psi.
