The System Consists of the Following Main Components:
- VDM NA100 type pumping unit for propane/butane with multifunction gland sealing and a capacity of 100 L/min, at a differential pressure of 14 bar under 1500 rpm.
- Input: DN 50, PN 40, DIN 2635.
- Output: DN 32, PN 40, DIN 2635.
- Explosion-proof electric motor of 5.5 kW, EEx e II T3, 230/400V, 50 Hz, IP 55, 1500 rpm, with coupling and protective casing.
- Liquid phase inlet DN50 with a ball valve DN50.
- Liquid phase outlet DN25 with a ball valve DN25 and a check valve.
- Bypass line with a valve.
- By-pass pipe outlet with a ball valve DN25 on the tank connection line.
- Vapour phase pipe with a ball valve DN20 on the tank connection line.
- Vapour phase compensating pipe assembly DN20 with a filling coupling M 60x4.0, left-hand, with a protective cover.
- Filling pipe DN50 with a ball valve DN50, a check valve and a screwed coupling M 60x4, left-hand, with a protective cover.
