Heavy duty slurry pump
ZD (ZDT) heavy duty slurry pumps are designed for the power, metallurgical, coal and construction materials industries to pump neutral or alkaline slurries containing solids. Optimized design, high efficiency, simple structure, easy maintenance, low operating costs. The ZD (ZDT) series is suitable for both atmospheric and low fluid density applications and can only be used as a stand-alone pump set.
■Flow rate: Q=10～1000 （m³/h）
■Total head: H=20～60 (m)
■S.g.: γ ≤1.23
■Pump diameter: 25～300mm
■Pump for conveying neutral or alkali slurries with solids.
■Bracket structure with single casing, easy for disassembly.
■Horizontal structure with a big loading capacity.
■Optimized hydraulic models of wide applicability.
■Heavy duty shaft with better performance in strength.
■Low pump speed and linear speed design to reduce the abrasion of pump.
■Various anti-abrasion materials for different applications.
■Single casing design. The casing and guard plate are working as anti-abrasive parts without outer frame.
■GB standard flanges, inlet pressure 1.6 MPa,outlet pressure 2.5 MPa;
■Shaft sealing: Dynamic seal, packing seal and mechanical seal.
■Transmission: Direct coupled, V-belt drive, variable frequency drive, hydraulic coupling.
