Product Description

Introduction:

Modern industrial equipment process request centrifugal pump are basically 

work under condition of variable flow, which needs set up automatic control 

devices in the process. However, when centrifugal pump under low load 

operation will appear overheating, serious noise, unstable and erosion which 

caused damage of pump. At this moment needs a kind of automatic recycle 

equipment, when pump under low load operation, through the bypass realize 

pump minimum flow backflow cycle. ZD series pump protection valve can 

prevent prevent overheating, serious noise, unstable and erosion damage 

of centrifugal pump under low load operation.As long as the flow rate of 

the pump valve below a certain value, the bypass backflow mouth will

 automatically open to ensure necessary minimum flow of pump.

Usage

■ Chemical industry                        

■ Petrochemical industry                

 Steel factory                          

■ Fire protection system

■ Traditional power plant

■ Paper-making industry

■ Shipment/shipping

■ Environmental protection industry

 

Three protection ways for pump 

■ Continuous circulating system

Minimum requirement of continuous circulating system pump is unrelated

 with the discharge of Process flow changes system. After setting of

 minimum flow, through orifice plate directly backflow to storage tank. 

Although continuous minimum flow circulation can protect pump very 

good,but pump must provide greater power output to ensure system 

process flow plus recycle flow, which causing additional energy waste. 

■ Control circulating system

Control circulatory system is assembly by the check valve, flow gauge, 

minimum flow control valve, control circulation system, control circulation

 system can provide minimum flow protection, when process flow is

 greater than minimum flow of pump, loop closed, no extra energy loss. 

But system is complex, control components, purchase, installation, 

maintenance cost is higher. 

■ Automatic Recycle Valve system 

Automatic Recycle valve set check valve, flow perception

, bypass control valve, multi-stage step-down in one, do not need power, 

control system and wiring, essential safety.Take up little space, which

 reduced the possibility of high speed fluid to malfunction to minimum. 

Installation and maintenance cost is low, is the priority pump protection 

way of modern industrial process.
