Pumps selections for propane delivery trucks
Corken has a long history of providing sliding vane pumps for Propane Delivery Trucks (e.g. bobtails). Currently these pumps are designated as our “Z” model line that consists of the Z4200, Z3200, and Z2000.
The propane transport typically uses a Z4200 (4” ANSI flange inlet) Coro-Vane pump mounted directly to the bottom of the tank and a bobtail typically uses a Z3200 (3” ANSI flange inlet) Coro-Vane pump mounted directly to the bottom of the tank. The bobtail can also use a Z2000 (2” NPT inlet) foot-mounted pump mounted on the chassis of the truck and piped to the bottom of the tank. These pumps are driven either by a PTO connection coming from the truck’s engine or by a hydraulic motor direct mounted to the pump. There would be a hydraulic pump system mounted on the truck to drive the motor on the pump.
The trucks are also equipped with meters that measure the amount of gas being dispensed for point of custody transfer and/or billing purposes.
