Sand, Sludge and Slurry Pump
    2. ZA Series Heavy Duty Slurry PumpZA(R) series heavy duty slurry pump are of single-stage, single-suction, cantilever, double casing and horizontal centrifugal pump, and this series products can transfer high corrosion and density slurry which are widely used in mining, coal, electricity, building materials and other industries.
    2. ZL Series Light Duty Sludge and Slurry PumpZL(R) series light duty sludge and slurry pump are single-stage, single-suction, cantilever, double casing and horizontal centrifugal slurry pump which apply to operating conditions of large flow, low concentration and lower head. When the speed is low, this pump can transmit slurry of strong abrasion and high density.
    2. ZM Series Middle Duty Sludge and Slurry PumpZM(R) series middle duty sludge and slurry pump are single-stage, single-suction, cantilever, double casing and horizontal centrifugal slurry pump, applying to large flow, low concentration and lower head operating conditions. Under low speed, ZM type slurry pump can transmit strong abrasion and high density slurry.
    2. ZH Series High Head Slurry Pump ZH series pump is a kind of single stage, single suction, cantilever, double casing, horizontal centrifugal slurry pump for transporting strong abrasive slurry, which is suitable for low flow and high concentration working conditions, especially for the high head conditions where general single-stage pump is not applicable.
    2. ZG(H) Series Sand, Gravel and Slurry PumpZG/ZGH series sand, gravel and slurry pump is a single-stage, single suction, cantilever, horizontal, centrifugal slurry pump, mainly used for conveying strong abrasive particles that are too big for general slurry pump to transport, such as granular coal, metal smelting slag and root crops.
    2. ZJ Series Sand and Slurry Pump ZJ series sand and slurry pump is a new type of anti-abrasion pump, belonging to axial, self-suction, single-stage, single suction, centrifugal slurry pumps. This series of pumps in the hydraulic design, structural design and the use of wear-resistant materials, combines the advantages of similar products at home and abroad.
    2. ZV Series Vertical Sump and Slurry Pump ZV series vertical sump and slurry pump is a single-stage, single suction, cantilever, vertical, centrifugal slurry pump, suitable for transporting abrasive, coarse particles, high concentration slurry, which does not need any seal water and can work normally in the condition of insufficient intake.
    2. ZF Series Forth Slurry PumpZF series forth slurry pump is a novel pump with high efficiency and energy saving. When working, it is able to eliminate the float slurry partly. So the ZF type pump has a transmission ability higher than other pumps, with no need of any shaft seal or seal water, being the ideal pump for transmitting forth slurry.
Flue Gas Desulphurization Pump
    2. Horizontal Slurry Pump in Flue Gas Desulphurization SystemDT series horizontal slurry pump adopts horizontal, single pump casing, single-stage single suction, bracket or suspension type structure, of which the maximum flow rate can be 12000m /h and the head is generally below 100m, covering all the working conditions of pumps in the desulfurization systems.
    2. Vertical Slurry Pump in Flue Gas Desulphurization SystemTL series vertical slurry pump adopts vertical, axial suction, single-stage single suction, single pump casing and centrifugal structure, suitable for the working conditions where the flow quantity is within 4m3/h-360m3/h and the head within 3m-82m, which can be used as absorption tower large slurry circulating pump.
Dredge Pump
    2. WN Series Dredge PumpWN(Q) series dredge pump is a new type of dredge pump developed by our company aiming at dredge pumps of dredging and hydraulic fill industries. This series of pumps, made of high strength wear resistant alloy cast iron (KmTBCr27), with its hardness not less than 58HRC.
    2. ZG Series Sand and Gravel PumpZG(H) series sand and gravel pump is a single-stage, single suction, cantilever, horizontal, centrifugal slurry pump, mainly used for conveying strong abrasive particles that are too big for general slurry pump to transport, such as granular coal, metal smelting slag and root crops, as well as for dredger, river dredging, mining and other fields.
