PT Series Air Driven High-Flow Liquid Pumps
The PT series of liquid pump are very high-flow liquid pumps. They have a 250mm double acting air drive with a liquid end connected to each end of the air drive, making them almost twice as efficient as the PH series. They are capable of pressures in excess of 30,682 PSI / 2,116 BAR.
These pumps can be supplied with interconnecting tubing that connects both liquid inlets to a common port and both liquid outlets to a common port, making for a simple installation.
The ProTech Pump model number reflects the pump’s nominal pressure ratio, while the technical data indicates exact ratios. The outlet stall pressure is easy to set by adjusting the air drive pressure and by simply multiplying the pressure ratio by the air drive pressure, the nominal liquid pressure can be calculated.
High-Flow Liquid Pump Applications
PT pumps are generally used when more flow is required than that delivered by the corresponding PG or PGD series units. An important application for this series of high-flow air driven liquid pumps is methanol injection and LPG transfer.
