Hydratech Industries have designed a range of liquid test pacs for performing high pressure hydrostatic testing. Also known as hydrostatic test systems, they are highly portable and only require nominal air supply pressure to operate. Some models can even reach a maximum pressure of up to 100,000 psi. M Series Liquid Test Pac (1/3HP) – Pressure up to 15,000 psi. (1030 bar) – Flow rates up to 3 gpm. (12 l/min) – All Hydraulic Liquids, Water-plain or DI, Solvents, Mild Chemicals, Liquefied gases. – All models operate on an air drive of between 25—125 psi (1.8—9 bar). – Hand pump option available for applications requiring precision pressure control or where no air drive is available. A Series Liquid Test Pac (2HP) – Pressure up to 100,000 psi. (3100 bar) – Flow rates up to 5 gpm. (19 l/min) – All Hydraulic Liquids, Water-plain or DI, Solvents, Mild Chemicals, Liquefied gases. – By stacking air pistons in double or triple airheads, this pump range can be increased from 1.5HP to 2.2HP G Series Liquid Test Pac (6HP) – Pressure up to 10,000 psi. (700 bar) – Flow rates up to 23 gpm. (87 l/min) – All Hydraulic Fluids, Water-plain or DI, Solvents. 8-Series Liquid Test Pac (8HP) – Pressure up to 22,500 psi. (1530 bar) – Flow rates up to 12 gpm. (45 l/min) – All Hydraulic Fluids, Water-plain or DI, Solvents, Liquefied gases. – Displacement per stroke, double acting output and efficient use of drive air or gas gives this range a decided advantage over smaller pumps in the same pressure range.
