HEMCO slurry pumps are suitable for bentonite and slurry handling with flow rates as high as 600 cubic meters per hour which makes these pumps very effective for use with diaphragm wall trench cutter system. The slurry pumps can be conveniently controlled by VFD (Variable frequency drive) pump control system. Robust structure of components ensures long working life of the pump. The pump body and case are made of special cast steel alloy whereas pump body, belt case and the impeller are reinforced with wear resistant metal lining.

Special Structural Features

• A large impeller diameter with short overhang ensures rigidity of shaft and makes the pump very suiteable for high pumping requirements.
• Hardened stainless steel shaft sleeve with 'O' ring seals at both ends. A slip fit through the sleeve protects the shaft from the wear and corrosion.
• The deputy vanes at front and rear of impeller relieve seal pressure and minimize recirculation.
• Casing is made of ductile iron while the ribs help the casing to withstand high pressures.
• The wet parts are made of special high chrome alloys which make these parts highly resistant to abrasion and corrosion as well as impact forces, thereby leading to high service life of the pump under the toughest working environments.
• Impeller design takes into consideration high volume flow required from the pump and the concave vanes result in improved flow and corrosion resistance which in turn increase the durability of the pump.
