Submerged LPG System Explanation
All calculations assume atmospheric pressure is 1013 mbar (14.7 psi) and outside temperature 15ºC (59ºF).
Mixture is assumed to be 40% propane and 60% butane.
The pump-motor units are approved for use with butane and propane and any mix of butane and propane. It has
been assumed that automotive LPG consists predominantly of propane, butane, with small proportions of propene,
butenes and pentanes/pentenes.
Temperature range - 20ºC to + 40°C (-4°F to +104°F)
System pressure - Max. 2500 kPa (362 psi)
Electric connection and motor protection - according to local regulation, or: NEN 1010 & NEN 3413 (Electrical
components in Hazardous Areas), VDE 0100 & VDE 0165 (Electrical components in Hazardous Areas).
The pump-motor unit consists of two parts; the motor 50/60 Hz. 380 - 415 Vac (stator, rotor, electrical
connections and bearings) and the pump (17, 21 or 24 impellers). Motor and pump are enclosed in stainless steel
shells. The Red Jacket submersible Premier, Premier Mid-Flow or Premier Hi-Flow LPG pump is not repairable. The
pump and motor of all three must be replaced as a complete set, not individually.
The stator is fitted with a containment shell of sheet metal and the windings are fully cast in epoxy. The section
with the pigtail (discharge head) consists of a metal body (Ex ’d’ flameproof enclosure) and electrical connections.
The wires in the connectors are cast in epoxy. The rotor conductors are copper bars.
