Product Features
Optimized Hydraulic Design
The pump uses optimized hydraulic models together with advanced manufacturing processes to improve operating performance and support longer service life.
Reliable Mechanical Seal
The mechanical seal uses an alloy silicon carbide sealing face, while the auxiliary sealing ring is made from fluororubber. This configuration helps improve operating reliability and allows the pump to handle higher-temperature conveying conditions.
Stainless Steel Wetted Components
The pump's flow-passage components are manufactured from stamped and welded 304 stainless steel or 316 stainless steel plates. This construction allows the pump to be used for mildly corrosive media.
Compact and Lightweight Construction
The vertical configuration minimizes the required installation footprint. Its compact size and lightweight construction make handling and installation easier, while the design also contributes to lower operating noise and energy consumption.
Pipeline-Compatible Connections
The pump inlet and outlet are positioned on the same horizontal line as the pump base. This configuration allows the pump to be installed directly within a pipeline system.
Standard Motor
The use of a standard motor provides greater flexibility for users who need to configure the motor according to their specific application requirements.
