The Dickow WPC 831T was specifically designed for tanker truck unloading applications.  The compact single-stage side channel is ideal for the tight space constraints of tanker trucks.  Once the WPC pump is initially primed, the side channel pump will operate like a piston pulling vapor and liquid though the line ensuring no issues with vapor lock.  Maximum flow of 55 m3/hr (242 gpm) and maximum differential head of 110 m (~360 ft) are possible with the WPC 831T pumps.  The pumps have an operating temperature limit of 100 °C (212 °F) and pressure of 10 bar (145 psi).

The Dickow HZS/HZSA pumps are designed with volatile liquids in mind.  These multi-stage centrifugal mechanically sealed pumps have one side channel impeller that allows for the handling of entrained vapors reducing the likelihood of vapor lock.   The HZS top-suction top-discharge design offers self-priming capabilities once the pump is initially primed.  This design makes the pump ideal for tanker truck, rail car, or underground tank unloading applications, since the HZS can purge the suction line of air and vapor.  The HZS/HZSA pumps can offer flows up to 600 m3/hr (2,460 gpm) and differential heads up to 500 m (1,640 ft).  The  maximum operating temperature is 100 °C (212 °F) and the maximum operating pressure is 16 bar (232 psi).
