pump type MVP: is a vertical dry pit pump, single stage with metallic volute casing.
These pumps are mainly engineered for applications where large quantity of flow with high head is required to be handled. Main applications are in Lift irrigation, water supply schemes, circulating cooling water for power plants. MVP pumps consist of Spiral casing which is fabricated Mild steel or stainless steel if required and casted enclosed impeller which can be offered in different materials.

Metallic Volute pumps are engineered pump with very parts / subassemblies and hence are very simple in construction. Its construction can be grouped into three sections as follows:
The different components are volute casing, bottom suction cone, cover ring and draft tube, discharge tube.
The parts are impeller, impeller shaft sleeve, coupling and thrust / journal bearing, etc.
Pump cover, thrust bearing stool, bearing housing, mechanical seal and top suction cone, etc.
Pumps can be offered with direct drive or with Gear Box drive.
Model Pump study:
With the consideration of the high flow and the head developed by metallic volute pump, it is not possible to conduct performance test of proto pump at test lab. Proto pump performance is guaranteed by carrying out scale down model pump testing.
