Propeller Pumps type PV

APPLICATIONS

Manufacturing Program: LAND APPLICATIONS

Vertical propeller pumps for pumping clean and treated liquids, without the presence of important solid bodies such as: cooling water, drinking water, hot water, sea water, sewage, etc.

This pump can also be used wherever large volume of liquids need to be raised against comparatively small discharge heights.

Are specially appropiated as:

Pumps for circulations of cooling water

In power plants, refineries, industrial installations and chemical industries.

Pumps for handling raw water.

In irrigation projects, water treatment, fisheries and dry docks.

Pumps for drainage of rainwater.

In protection stations against floods.

For drainage of rainwater, and in waste water plants.

CHARACTERISTICS

Capacity Q = up to 10.000 m3/h.Height H = up to 12 mSpeed n = up to 1.500 r.p.m.

TECHNICAL DATA

Propeller Pumps type PVManufacturing Program: LAND APPLICATIONS

Transmission shaft

Designed for working below the first critical velocity. The union between them is achieved by means of muff no coupling. In the areas of contact with the radial bearings and the gaskets, the shaft is protected with sleeves.

By installing protecting tubes with airtight sealings the shafts unit can be isolated from the pumped medium.

The shaft tightness at the point it reaches the pump housing is assured by placing an easily accesible stuffing box in the discharge elbow.

Radial and thrust bearings

The weight of the pump rotor along with the resulting hydraulic thrust is supported by axial bearings amply dimensioned which have been calculated in such a way that its lifetime in normal working conditions is at least 30.000 hours.

Along with this bearing another with balls is installed as support to the radial force originating in the upper part of the pump. The lubrication if the bearings is in an oil bath and, depending on the axial thrust, the bearing holding can be supplied with or without refrigeration.

Bearings

The pump rotor is radially guided by various bearings situated in the volute chamber and spider.

The bearings can be manufactured in two classes:

a) Bronze bearings lubricated by grease.b) Rubber bearings lubricated by the pumped medium.

Design characteristics

Vertical propeller pumps, simple stage, for installation in deep wells.

Conforms to with the following normalisedelements:

Pump body, tube sections, column discharge elbow, support drive.

Optimum with removable rotor, type PVa, the rotating pieces unit along with the volute chamber can be dismounted through the tube column and the impeller elbow without needing to dismount the discharge tubes.

Propeller

Amply sized curved blades are set in the propeller head.

The adjustment of the blade angles permit variation of the pump characteristics within the limits as given in the curve characteristics.
