Product Details
DL Vertical Multistage Water Pump
DL/DLR vertical multi-stage centrifugal water pump adopts the
hydraulic model of the high-efficiency and energy-saving product IS
pump recommended by the country, and is a vertical multi-stage
multi-segment structure. The screw clamps the water inlet section,
the middle section and the water outlet section into a whole. Each
stage of the pump is equipped with an impeller and a guide vane.
The axial force is solved by the hydraulic balance method, and the
residual axial force is borne by the ball bearing and lubricated
with grease. The shaft seal adopts soft packing or mechanical seal.
The outlet of the same pump can be set with 1 to 5 outlets.
Model meaning of DL vertical multistage centrifugal pump:
For example: 150DLR150-30×3
150-inlet and outlet diameter
DL-vertical multistage centrifugal pump
R-hot
150-flow
30-single-stage head
3-stage
Application:
1. It is mainly used for high-rise building domestic water supply,
fire constant pressure water supply, automatic spray water,
automatic water curtain water supply, etc. It can also be used for
water supply and drainage in factories and mines, long-distance
water supply, supporting use of various equipment and water for
various production processes.
2. It is used to transport diluted, clean, non-corrosive,
non-explosive water and liquid without solid particles or fibers
with physical and chemical properties similar to water.
3. The medium temperature of the DL vertical multistage centrifugal
pump does not exceed 80℃, and the medium temperature of the DLR
multistage centrifugal pump does not exceed 120℃.
Working Condition:
1. The medium used in the DL/DLR series multistage centrifugal pump
should be similar to water, with a kinematic viscosity
<150mm2/s, and no hard particles, and no corrosive properties.
2. This machine is used at an altitude of less than 1000 meters, if
it exceeds, it should be mentioned in the order, so that the
factory can provide you with more reliable products.
3. The operating temperature of the medium is -15℃~120℃.
4. The maximum system working pressure≤2.5MPa.
5. The ambient temperature should be lower than 40℃, and the
relative humidity should be lower than 95%.
Feature:
1. DL/DLR vertical multi-stage pump has compact structure, small
size and beautiful appearance. Its vertical structure determines
the installation area is small, and its center of gravity coincides
with the center of the pump foot, thus enhancing the pump's
operational stability and service life.
2. Its suction and discharge ports are both horizontal, which
simplifies the connection of pipelines.
3. According to needs, the suction port and the discharge port can
be installed in the same direction or in different directions of
90°, 180°, 270° to meet different connection occasions.
4. The head of this pump can be increased or decreased according to
the needs and combined with the outer diameter of the cutting
impeller to meet the requirements, without changing the
installation area, which is not available in other pumps.
5. The motor is equipped with a rain cover, and the pump can be
used outdoors, eliminating the pump room and saving construction
costs.
6. The rotor of the this machine has a small deflection, and the
4-pole motor is selected, so it runs smoothly, with low vibration,
low noise and long service life.
