1. Product Introduction
Dongkai JXM/JZM Series Digital Auto Control Mechanical Diaphragm Metering Pumps. (with VFD Variable Frequency Drive)
5LPH@12Bar - 2000LPH@3Bar.
VFD Input Power: ModBus RS485 / 0-20mA / 0-10VDC / Liqiud Level
Motor (Powered by VFD): Single Phase AC110V/220V or 3-Phase 380V/410V/440V
4-20 mA or 0-10VDC signal input controls stroke frequency 10:1 Turn-Down
Manual stroke length adjustment (0 to 100%) 10:1 Turn-Down.
2.Product Parameter (Specification)
Manual control and automatic control both utilize 1/2 hp, TEFC motor which provides for a quiet and cool operation. This lightweight metering pump allows a 1000:1 turn down capability by using the MPC controller. The VFD automatic controller controls the pump speed and flow through a digital display. TheVFD uses digital (4 to 20 mA) inputs and outputs to monitor and control elements of the process.
The PVC model is ideal for pumping Sodium Hydroxide, Sulfuric acids in low concentrations, and Hyrdrochloric acids in low concentrations. Choose the stainless steel version for moving Acetic acids, and Lithium Cholrides.
3. Product Feature And Application
Digital Auto Control Mechanical Diaphragm Metering Pumps has the following characteristics:
Easy to Install, Rugged Construction
Simple, intuitive design is easy to operate and maintain. Oil free, greased for life bearing with no more oil to buy or change. Compact and lightweight. Designed to withstand both indoor or outdoor rigors (when protected from precipitation and direct sunlight).
Manual Stroke Adjustment Mechanism
Manual micrometer style stroke adjustment; 10:1 turndown.
Cartridge Check Valves
Guided ball check system reduces back flow and enhances priming characteristics. Simple o-ring seals provide for reliable leak free performance and easy replacement.

5.Product Qualification
signal input pin definiy
Pin 1 and pin 2 are respectively connected to the analog signal input terminal, which can be connected to 0~20mA current signal or 0~10VDC voltage signal. Among them, pin 1 is connected to the positive terminal of the signal, and pin 2 is connected to the negative terminal of the signal. The pin enables the system to support external analog signal input control;
Pin 3 and pin 5 are respectively connected to the signal input end of the passive dry contact. This pin enables the system to support the start/stop control of the pump in the external signal control mode;
Pin 6 and pin 7 are respectively connected to the signal input terminal of RS485 communication line, pin 6 is connected to RS485 A+ terminal, and pin 7 is connected to RS485 B-terminal. This pin enables the system to support RS485 communication control and Modbus communication protocol;
