Product description

Horizontal-inlet/vertical-outlet, non-self-priming, multistage, monobloc, horizontal high-pressure centrifugal pump. Compact pump with a through-shaft mechanical seal independent of the direction of rotation. Suitable for water supply and pressure boosting in industrial circulation systems, process water circuits, and closed cooling circuits. Can also be used in washing systems, irrigation, and water conditioning.

Features/Product advantages: Space-saving compact monobloc design. All hydraulic parts and fluid-contact components — e.g. stage chambers, impellers, main impellers, and pump casing — are stainless steel. Drinking water approval (ACS, KTW, WRAS) for all fluid-contact components (EPDM model).
