3 – VaporTEK System Description
VaporTEK Pump
The VaporTEK pump is a variable-speed piston pump capable of drawing up to
120 LPM of vapor through a vapor recovery nozzle and delivering it to the UST at the
dispensing site. The piston pump works on the floating piston principle, i.e., piston rod and
piston form a rigid unit. On each complete rotation of the shaft, the gas mixture is aspirated at
the inlet valve and compressed in the cylinder. The inlet or outlet valve blocks a flow
direction, i.e., the aspirated gas mixture is expelled via the outlet side of the pump.
The following are the features/requirements of the VaporTEK pump:
• The ambient and the inlet temperature must not exceed 130 °F (55 °C).
• The gas temperature in the outlet line must not exceed 203 °F (95 °C).
• The maximum pressure with closed discharge shall not exceed 1600 mbar (g) at any
speed.
• The inlet/outlet ports have standard National Pipe Thread (NPT) 3/8-inch female threads.
