Materials
For the axial split case pump:
- Impeller made of bronze CuSn10
- Pump housing made of cast iron GG 30
- Shaft made of stainless steel AISI 410
- Shaft sleve made of stainless steel AISI 410
- Wear rings made of bronze
For the norm pump in back-pull-out design:
- Impeller made of bronze CuSn10 or CuAl10Fe5Ni5
- Neck ring made of stainless steel AISI316L/1.4409
- Pump housing made of cast iron EN-GJL-250
- Shaft made of stainless steel AISI420/1.4021
For the jockey pump:
- Impeller made of stainless steel AISI 304/1.4301
- pump housing of stainless steel AISI 304/1.4301
- Shaft made of stainless steel AISI 304/1.4301

Construction
- Base frame: Produced from epoxy-coated or optional galvanised steel profiles with brackets for the switchgear. Slinging points (eyelets) for lifting accessories pre-assembled. Special baseplate for the pump driven by the diesel motor, designed to intake large quantities of concrete (option for NFPA20 execution only), significantly reducing vibration transfer and increasing the product’s reliability and service life.
- Pumps: 1 pump with horizontal baseplate with an electric or diesel motor. Pump with split housing or axial discharge for easy access to the inner pump components without having to dismantle the motor or piping
- Tank: Fuel tank made from epoxy-coated steel with a strong support structure. Fully equipped with a fuel gauge, drain plugs and air vent valves.
- Sensors and display: The pressure sensors are located next to the switchgear or mounted on the wet column and activate the pump start via the controller. The pressure gauge on the suction and discharge side (ø 63 mm) is located on the pump’s split housing (only NFPA 20 execution).
- Control device/controller: The pump kit is standard-equipped with a switchgear for the electric or diesel motor.
