The DS series multi-purpose mud and sand pump is a single-stage, single suction, centrifugal pump, divided into 4 inches, 8 inches, 1 inch, 12 inches, and 14 inches according to the outlet diameter. 16 inch, 18 inch, 20 inch and other major series with multiple specifications. This pump has innovations in hydraulic design and structural design. The flow passage components are made of wear-resistant high chromium alloy casting, which has the characteristics of energy saving, wear resistance, and reliable operation. It is suitable for conveying strongly abrasive mortar, grout, ore tunnels, etc. containing solid particles. The solid-liquid mixture concentration conveyed can reach 60%, making it an ideal sand pumping and conveying equipment. Users can use single or multiple machines in series operation according to actual working conditions to achieve long-distance construction. Widely used in sand pumping, national land reclamation, power fly ash transportation, metallurgical industry tailings transportation, etc. 1. DS series multi-purpose mud and sand pump: The pump body adopts an inner and outer double-layer metal structure, the pump casing is vertically split, and the outlet position is installed by rotating at intervals of 45. 2. Shaft seals can be classified into three types based on different working conditions: secondary impeller shaft seals, packing shaft seals, and mechanical seals. 3. Adopting a closed impeller, it has good wear resistance and high pump efficiency.
