With a wide selection of materials and shaft sealing system Chemical pumps are suitable to handle nearly all kind of liquids which are usual in the above mentioned industries. For example we call acids, lyes, solvents, hydrocarbons, heat transfer liquids, heavy fuel, liquid sulphur, melted plastics, bitumen a.s.o.

Construction

The Chemical standard pumps are single-stage, single-flow volute casing pumps in back pull out design, with an end suction flange and a centerline discharge flange. Bearing housing with intermediate casing, shaft sealing and impeller is mounted to one unit. With the back pull out design unit can be removed without demounting the pipe connections. If spacer type couplings are used, the driver can also remain bolted on the base plate.

Volute casing

The pump casing of standard design is cast in one piece and foot mounted on the base plate. The casing is sealed to the atmosphere by confined non-asbestos gaskets. If required, following special designs are available: Volute casing with heating jacket Pumps with heating jacket are required if the liquid temperature decreases when flowing through the pump or when the liquid temperature drops below the For example: Dimethylterephthalat (DMT), sulphuric liquid, etc. Heating jackets on volute and intermediate casings with welded cover are designed for heating liquids up to 24 bar/350 psi and 220
