1.Hydraulic diaphragm Series
Hydraulic diaphragm Series is a hydraulic transmission membrane, through the hydraulic oil (or other suitable medium) connecting the diaphragm and the plunger, diaphragm plunger given by the oil pressure pulsation reciprocates between the plunger and diaphragm There is no mechanical connection between.

precise automatic control system for the built-in compensation valve for accurate control to ensure that the diaphragm is not overloaded, some of the harsh conditions, such as clogged or outlet valve is shut will happen even in the pump failure. Because compensation valve only reached the end of the suction stroke when the diaphragm will be driven, that is exposed to the diaphragm stopper pin will put the compensation valve is opened. This prevents hydraulic system overload, ensure the membrane life of 10,000 hours.

Hydraulic diaphragm pump diaphragm stress, not dependent on the suction pressure does not depend on the exclusion of pressure, but depending on the deformation of its sides generated by the pressure difference may be. Thus, almost no limit to the practical application of this type of pump。

Pump the hydraulic system is equipped with a built-in safety valve to protect the pump head and gear mechanism in case of overload. Automatic oil and built-in security system built-in safety valve mutual intermodal - using the diaphragm - stop valve - compensation valve. This protection system can be safely used in low, fluid, high viscosity, it can also be used for measuring turbid solution and suspensions of various delivery。



Hydraulic double diaphragm alarm series

Hydraulic double diaphragm metering pumps are suitable for alarm strong adhesive mud, high viscosity media, sterile pharmaceuticals, will react violently with hydraulic fluid medium and when the diaphragm damage will lead to dangerous situations. All performance with a single diaphragm pump, but also has its own characteristics. The use of the intermediate chamber, can any one。




2.Plunger type series
Fluid end performance plunger metering pumps

Controlled pressure, high measuring accuracy, simple structure, easy maintenance, wide application and has high practicality and economy. High temperature ceramic plunger spray (Note: When the transmission medium exceeds 100 ℃, JIAOZHI chrome plated stainless steel piston); German import filler; JIAOZHI filler with automatic reset system: When a gap appears between the filler and plunger wear, automatic reset device can be adjusted immediately to its original working state, so as to effectively prevent media leaks。

When the piston head of media delivery requires heat or cooling, it can be used with insulation jacket。



Insulation cooling jacket plunger泵头

It is a special design of piston metering pumps. In the liquid cylinder with cooling interlayer insulation housing on the import and export, transport medium can be special insulation or cooling. While its sealed chamber with heat or cooling jacket, through the delivery of heat or cooling medium jacket to control the temperature of the seal chamber. Steam heating insulation is relatively stable, the transmission medium temperature difference is relatively small. It is mainly used to transport large to be heated or viscosity and the viscosity decreases with increasing temperature of the medium. But also for special insulation design, specially designed casing jacket and sealing device is suitable for easy crystal, thermal transfer medium required according to the user's needs.



3.Mechanical Diaphragm Series

Economical and reliable
Mechanically driven single and double diaphragm metering pumps, diaphragm pumps not only has advantages and security (operating pressure up to 1.2MPa, the maximum flow rate of up to 2500L / h), and high economy.

Application

    • 1.Prevent pump seal particles and lubricants into the delivery medium, such as drinking, sewage treatment industry。
    • 2.When transporting dangerous media, require the pump completely leak。
    • 3.To meet the high operational safety and reliability provided economic choice。

    Advantage

    1. High operational safety


4.Transmission metering pump

UCam drive mechanism

    • Motor, worm gear。
    • UCam mechanism structure adjustment is simple, easy operation, good price。
    • Linear stroke adjustment with high precision and reproducibility。
    • Whether or running in the park, you can travel between any regulation 0 to 100%。

      Telescopic drive mechanism

      1. Motor-driven eccentric crank combined worm gear integrated, ensuring low noise pump


5.Flow regulation system

Flow regulation system

With a variety of control systems, you can manually, frequency, power, automatic control to regulate the flow. Turndown ratio of 10: 1, regulation accuracy ± 0.5%. Stepless adjustment.
 



Manual control system
Metering pump is running or stopped state, the stroke length can be adjusted manually, Exact dosage adjustment, adjustment range 0 to 100%

Frequency Control System
可外接变频器接受4~20mA、0~20mA控制信号,
实现自动调节行程频次;调节范围25%~100%。
