LPG Transfer Pumps
Z Series LPG Pumps
Volumetric Vane Pump Range — Z1000 to Z4200
The Z series liquefied petroleum gas pumps are volumetric vane pumps with an advanced structure, mainly used to transport LPG, propylene and liquid ammonia, and suitable for drainage or transportation of volatile liquids and similar petroleum products. The stator curved surface uses a composite curve with mechanical seals at both ends and O-shaped seal rings at all fixed joint faces, for safe, reliable and multi-purpose use.
