Product Introduction

SDL,SDLRType vertical multistage centrifugal pump, has the advantages of compact structure, low noise, smooth operation, small footprint. This series of products adopts excellent hydraulic model, which has the characteristics of high operating efficiency, wide efficient area and light performance coverage, and can operate for a long time under efficient and economical working conditions.

SDLRType for high temperature type vertical multistage pump, mainly used for conveying liquid temperature≤ 150 °C, Non-corrosive, physical and chemical properties similar to clear water liquid, used in heating circulating water, condensed water, residual hot water transportation.

SDLType for ordinary vertical multi-stage pump, used for conveying liquid temperature≤ 80 °C, Non-corrosive, physical and chemical properties are similar to clear water, suitable for floor fire domestic water supply, air conditioning unit cooling circulating water delivery.

Product Features

Vertical multistage centrifugal pump is a centrifugal pump with compact structure, small size, light weight, low noise, significant energy saving effect and convenient maintenance. It adopts standard vertical motor and quick-loading mechanical seal, which is very convenient to replace. The flow part of the pump is made of stainless steel (304\316) made of materials, suitable for mildly corrosive media.

1. The vertical type adopts excellent hydraulic model and advanced manufacturing technology, which greatly improves the performance and service life of the pump.

2, because the shaft seal is made of hard alloy and fluorine rubber mechanical seal It can improve the reliability of pump operation and the temperature of the conveying medium.

3. The flow part of the pump is stamped and welded with stainless steel plate, which makes the pump suitable for mild corrosive media.

4. The overall structure is compact, small in size, light in weight, low in noise, significant energy saving effect, and convenient maintenance.

5. The water inlet and outlet of the pump are located on the same horizontal line of the pump seat and can be directly used in the pipeline.

6. The standard motor is adopted, and the user can easily equip the motor according to the need.

7, can be equipped with intelligent protector according to user needs, the pump dry, lack of phase, overload and other effective protection.

Structure Description

Normal temperature type and high temperature type vertical multistage centrifugal pump are supported at both ends, and the shell part is segmental. The transmission mode of the pump is connected with the motor through the elastic coupling. See diagram for pump structure description3.

1, Stator part:

It is mainly composed of suction section, middle section, discharge section, guide vane, stuffing box body, bearing parts, etc., which are respectively connected into one body by tightening bolts and bolts. The discharge outlets are vertical upward, the suction inlet of the room temperature type bedroom multi-stage pump is horizontal, the suction inlet of the high temperature type bedroom multi-stage pump is vertical upward, and the suction inlet and discharge outlet of the vertical multi-stage pump are horizontal.

2, Rotor section

Mainly composed of shaft, impeller, balance plate and shaft sleeve and other parts

3, Seal of pump

The static joint surface between suction section, middle section and discharge section shall be sealed with paper pad.
Throttling seal is adopted between all stages of pump.
Water retaining ring is used to prevent water from entering the bearing chamber.
This series of pumps have two kinds of packing seal structure and mechanical seal structure. Packing seal structure before the operation of the pump, the need to be higher than the atmospheric pressure of water through the water seal pipe, into the suction section and the packing chamber of the stuffing box, sealing and lubrication.
Mechanical seal structure, mechanical seal can be used in the assembly type mechanical seal, easy assembly, maintenance. A user-supplied mechanical seal may also be employed.

4, Cooling system

Because the temperature of the liquid transported by the high temperature pump can reach105℃In order to prevent the bearings at both ends of the pump from overheating and damage, this type of pump is equipped with a cooling system. If the bearing temperature exceeds 75℃ Cooling water can be filled into the water cooling chamber and water cooling pipe at both ends of the pump to cool the stator and shaft respectively.

5. Bearing part

The entire rotor is supported by bearings at both ends of the shaft. The rolling bearings are lubricated with grease. Sliding bearing used N46 machine oil lubrication
