QDLF Vertical stainless steel multistage centrifugal pump

QDLF vertical stainless steel multistage pump is designed according to the
advantages of ISG vertical centrifugal pump and DL vertical multistage centrifugal
pump. In the structure, it adopts the vertical and segmented form. The suction
inlet and discharge outlet of the pump are designed into the same level and a good
hydraulic model is adopted. The axial force of the pump is solved by hydraulic
balance method and the residual axial force is borne by a ball bearing, so the
operation is stable, low noise, small occupation area and convenient installation.

Vertical stainless steel multistage pump is made of stainless steel with beautiful
appearance,. The pump is especially suitable for high-rise building multi-pump in
parallel use, to reduce the power of single pump unit, simplify electric control
equipment. It is suitable for fire fighting, domestic water supply, air
conditioning unit circulation and cooling water transportation of high and low
floor buildings, hospitals, hotels, department stores, office buildings, etc.

Features of stainless steel multistage pump

1, the use of excellent hydraulic model and advanced manufacturing technology,
greatly improve the pump performance and service life.

2. The shaft seals adopt mechanical seals made of hard alloy and fluororubber,
which can improve the reliability of pump operation and the temperature of
conveying medium.

3. The over-flow part of the pump is made of stamping and welding of stainless
steel plate, which makes the pump suitable for mildly corrosive medium.

4. Compact overall structure, small volume, light weight, low noise, significant
energy saving effect, convenient maintenance.

5. The inlet and outlet of the pump are located at the same level of the pump
base, which can be directly used in the pipeline.

6. Standard motor is adopted, which can be conveniently equipped by users
according to their needs.

7. It can be equipped with intelligent protector according to users' needs to
effectively protect pump dry rotation, phase loss and overload.

Vertical stainless steel multistage pump for water supply

Water plant filtration and transmission, water plant zone water supply,
supercharging, high - rise building supercharging.

Industrial supercharging: process water system, cleaning system, high pressure
flushing system, fire fighting system.

Industrial liquid transport: cooling and air conditioning system, boiler feed
water and condensation system, supporting machine tools, acid and alkaline medium
transport.

Water treatment: ultrafiltration system, reverse osmosis system, distillation
system, separator and swimming pool water treatment system.

Irrigation: irrigation, spray irrigation, drip irrigation.

Vertical stainless steel multistage pump service conditions

1. Medium temperature: -15 to 120 degree Celsius.

2. Ambient temperature: +40 degree Celsius.

3. Overall pressure: 10bar.

4. Large import pressure is limited by the environment pressure.

5, when the density or viscosity of the transmission medium is greater than water,
need to consider the use of a larger power motor.

The medium

1. Thin, clean, non-flammable and explosive medium without solid particles or
fibers.

2, such as mineral water, softening water, pure water, oil and other light
chemical medium.

3, vertical stainless steel multistage pump main material is stainless steel, can
be used for pumping mildly corrosive medium.

The motor is fully enclosed, air-cooled diode standard motor protection grade:
IP55 insulation grade: F standard voltage (50Hz) : single-phase 220V, three-phase
220V/380V

Minimum Order: 1 sets
