LHY sulfur submersible pump

1、 LHY sulfurSubmersible pumpsketch

LHY sulfur submersible pump is suitable for transporting liquid sulfur at 130-158 degrees Celsius in various scales of sulfur based sulfuric acid production processes. It is also applicable to other chemical processes that require small flow rates and high head. Due to its extremely high head, small flow rate, and low specific speed, it is no longer possible to achieve performance requirements using a centrifugal pump for LHY liquid sulfur pumps. Using a vortex pump would result in unstable performance during operation, so a new technology was adopted for ineffective design, which has special advantages that ordinary centrifugal pumps and vortex pumps do not possess.

When the flow rate of the liquid sulfur pump varies greatly, the head of the pump remains constant. This feature is particularly suitable for chemical processes that require pumps to have self-adjusting characteristics.

3、 Structural characteristics of LHY sulfur submersible pump

1. This series of pumps is a vertical insulated submersible pump. The outlet pipe of the pump is equipped with steam or thermal oil insulation jacket from the pump body and front pump cover.
2. This series of pumps mainly consists of pump body, impeller, front pump cover, pump shaft, bend pipe, outlet pipe, intermediate connecting pipe, bottom plate and bearing box, motor seat and other components.
3. The impeller of this series of pumps is a star shaped structure. Its structure is simple and easy to manufacture. The impeller is equipped with balance holes to balance the axial force, which can be considered completely balanced, providing great benefits for the operation of the pump.
4. This series rotates counterclockwise when viewed from the motor end.
5. The installation dimensions of this series of pumps can be customized according to the customer's usage requirements.

4、 Other instructions for LHY liquid sulfur pump

Sulfur based sulfuric acid production is one of the important development directions of China's sulfuric acid industry. Low flow, high head liquid sulfur pumps are key equipment for sulfur based sulfuric acid production. In order to meet the needs of this situation, with the joint efforts of relevant design institutes, experts from colleges and universities, and our factory staff, we have developed the LHY series vertical liquid sulfur pumps.

The LHY insulation liquid sulfur pump has a simple structure, easy maintenance, smooth operation, and stable performance.

This series of pumps is made of 1Cr18Ni9Ti material when transporting liquid sulfur. When used in other chemical processes, the following materials can be used for manufacturing:
304 (0Cr18Ni9) 316 (0Cr18Ni12Mo2)
1Cr18Ni12Mo2Ti 316L (00Cr18Ni12Mo2)
CW-2 (CD4MCU) J-1 (UB-6)

When transporting liquid sulfur and other flammable media, this pump generally uses YB series explosion-proof motors, and other types of motors can also be selected according to user requirements.
Performance range:
Flow rate: 0.1-200m3/h
Head: 40-200m
Speed: 2900r/min
Applicable temperature range: t<=200 degrees. If special manufacturing technology is used, the applicable temperature can be increased to 550 degrees.
