DSV typeSingle stage ,Vertical

Axially split case double suction pump

High efficiency and low pulsation

Wind performance range with up to 280m head

Stable service and low maintenance

Heavy duty design and long life span

Options for CW /CCW rotation

Fine production and shortest downtime

Vertical construction to save the landing

General Description

DSV is the vertical single stage axial split casing centrifugal pumps with double suction impeller. The

casing is axially split, so it allows to maintain the pump without dismantling the pump from the whole water

system. It has reasonable compact structure and can rotate clockwise or anti-clockwise to meet the

different site condition. The shafts are sealed by reliable mechanical seal or gland packing. According to

different applications, the bearings can be lubricated by grease or thin oil. DSV pump is excellent split

case pump that are widely used in large amount water transportation, water lifting, fire fighting in water

plant, offshore project, mining, factories and so on.

Design features

Vertical construction

Heavy design axially split case

Optimized double suction impeller

Stuffing box and positive sealing

Vertical construction request less landing.

Double volute casing (size dependent) avoid

the radial hit to the rotor so prolong the life time

of the pump and more reliable performance.

Casing is axially split, so it is easy to do

maintenance the replace the parts.

The double suction impeller has optimized

hydraulic performance and high efficiency. The

double suction remove the axial hydraulic

thrust to the rotor and protect the pump.

The positive sealing is from the impeller, shaft

sleeve and casing ensure non-leakage.

The stuffing box is suitable to single

mechanical seal, cartridge seal and soft

packing

Bearing assembly

Renewable wear ring

Reinforced shaft

Shaft sleeve

The upper bearings are standard with greased

type rolling element from SKF /FAG /NSK /

NTN. The lower bearing is optional for ball

bearing or water lubricated sleeve type

bearing.

The renewable wear ring is positioned to the

casing by the pins, easy to replace. Casing

wear ring is optional if it is necessary.

The shaft is designed for heavy duty service

driving and suitable for constant speed and

variable speed driver.

Stainless steel or bronze protect the shaft.

There is O-ring between the sleeve, impeller

and shaft.

Construction A

The lower bearing is rolling bearing lubricated by grease.

Construction A

The lower bearing is sleeve type bearing lubricated by water pumped
