CVX

Utilisation

The CVX pumps are designed for delivery of clear and also slightly polluted water with temperature up to 90°C and pH value raging from 6,5 to 8,5. Permissible content of impurities is up to 1% volu-me of sludge with non-abrasive solid particles with max. grain size of 0,5 mm. The standard utilisation of these pumps is in water systems, power engineering and agriculture for delivery of drinking and service water to various objects or pumping stations of irrigation sets, re-pumping in mining plants etc.

Technical description

The multistage centrifugal horizontal CVX pumps are in configuration with radial impellers, rotor, stator, bearings and stuffing box. The rotor consists of shaft with impellers, sealing cases and shaft bushing. The whole set includes also internal bearing rings with nuts. The stator consists of individual stages and stage jackets provided with flat sealing fixed between the suction and delivery body by means of fixing bolts and nuts. The antifriction bearings are greased and without cooling.

Material

The CVX pumps are available in material modification according to LN or ON 11 0003 standards. Main parts are made of grey cast iron or structural steel, seal cases of chrome steel.

Stuffing box

The CVX pumps are provided with soft seals. The sealing material is usually chosen according to properties of a pumped liquid and its temperature. The presealing spaces of the delivery and suction pump seals are interconnected.

Technical parameters
