Design Characteristics Single stage centrifugal. Casing axially split. Double entry impeller. Bearings on both sides of impeller. Suction and discharge branches located in lower casing.

1 Design Characteristics Single stage centrifugal. Casing axially split. Double entry impeller. Bearings on both sides of impeller. Suction and discharge branches located in lower casing. Características de funcionamiento Capacities Q= m3/h. Head H= up to 200 m Speed n= r.p.m. Temperature t= up to 150ºC Pressure p= up to 25 bar Aplicaciones Handling clean or slightly dirty liquids, without the presence of significant solid bodies, such as cooling water, drinking water, hot water, raw water, caustic solutions, hydrocarbons, crude oils, etc. Specially appropiate for: irrigation, municipal supplies, general industries, electrical stations, heating, drainage previously hacked, cooling towers, refineries, chemical plants, shipping industries, etc..: P. 0 :.

2 TECHNICAL DATA Casing Single stage, spiral or volute, axially split. Replaceable casing wear rings. Flange dimensions accordance to DIN, ANSI, BS, etc. Double volute casing can be incorporated in special. Impeller Double entry, closed impeller, with helicoidal vanes. Special design with impeller wear rings. Shaft sealing Soft packing stuffing box with connection for sealing liquid or mechanical seal of various types and makes. Bearings Shaft supported in amply dimensioned grease or oil-lubricated antifriction bearings. In special cases the bearing housing can be cooled, thus providing cold water through a leekproof chamber designed for the purpose. Direction of rotation Normally clockwise (CW) when viewed from the driver end, counter clockwise (CCW) possible. Driver The driver can be obtained equally by means of an electrical motor, turbine or explosion engine. Coupling Standard three part flexible coupling are installed. Spacer-type coupling can also be installed..: P. 1 :.

3 Special executions Apart from the standard horizontal execution, the ZM pumps can also be installed in other positions as shown below, making small changes in the basic design. In all these cases Hidrotecar should be consulted..: P. 2 :.
