The metering pump is a high-precision quantitative injection pump that can quantitatively infuse or meter various liquids with different chemical and physical properties. The precision metering pump is a forward plunger type pump, and the typical structure is divided into a one-way valve type pump and a rotary valve type pump. One-way valve pumps are used for low to medium viscosity liquids with a viscosity range of 1 to 10,000 cps. Rotary valve types are used for liquids with high viscosity or solid particles, with viscosities ranging from 100 to 50,000 cps. The unique and compact design of precision metering pumps uses a variety of high-purity, high-quality, corrosion-resistant materials to achieve a wide range of liquid injection functions and superior performance: Micrometer capacity regulators, making it highly accurate and repeatable Sex; actual measurement accuracy is higher than the nominal plus or minus five-thousandths of a millimeter, some models of pumps (such as: MD type) can still achieve very high accuracy at 1 microliter injection volume. Independent speed control components enable injection under various conditions. The non-abrasive design and sturdy construction allows the precision metering pump to operate millions or even 20 million times without maintenance.

Servo-drive precision metering pumps are developed on the basis of traditional pneumatic metering pumps. All pneumatically driven metering pumps have servo-driven metering pumps of the same specifications. Servo-driven pumps exhibit more stable injection performance than pneumatically driven pumps. In the automatic control and production management shows more excellent features.

Precision metering pumps are typically used for the following liquids:

General industry: electrolytes, capacitors, acids, alkalis, reagents, paints, coatings, glues, adhesives, fluxes, butter/oil, photographic fluids, Freon;

Cosmetics: perfumes, creams, skin care products, shampoo, lipsticks, cleansing nets, mascara, nail polish, etc.

Food: tomato juice, mustard, seasonings, pulp, honey, butter, fruit puree, juice, pudding, yogurt and so on.

Pharmaceuticals: Plasma, cultured antibiotic vaccines, biological agents, antibiotics, oral liquids, etc.

Metering pumps mainly have the following series of models: (There are also some special metering pumps with additional instructions)

One, 1BC/2BC series one-way valve type pump, suitable for the quantitative injection of various low-viscosity liquids (1-20.000CPS) without particles, in which 1BC series pump injection range is 0-2.5 ml, 2BC series The pump injection range is 0-20 ml, which can be infinitely adjusted by the micrometer capacity adjuster within the capacity range.

Second, 1BR/2BR rotary valve pump, suitable for a variety of medium and high viscosity liquid (100-100.000CPS) or quantitative liquid containing particles. 1BR series pump injection volume range is 0-2.5 ml, 2BR series pump injection range is 0-20 ml, in the capacity range through the micrometer capacity regulator to achieve stepless adjustment.

Third, 4H-CV series one-way valve pump, suitable for a variety of particle-free medium and low viscosity liquid (1 - 20.000CPS) of the quantitative injection of liquid injection range is 0-260 ml, injection range is 0-260 Ml.

Fourth, 4H-RV rotary valve type pump, suitable for a variety of medium and high viscosity liquid (100-100.000CPS) or quantitative liquid containing granular liquid. The injection range is 0-260 ml and the injection range is 0-260 ml.

Fifth, servo-driven check valve series pumps, servo drive precision screw mechanism, precision check valve control liquid input and output channels, effective measurement of low viscosity liquid infusion. A color touch screen controller can be connected to control 1-64 sets, easy to set any injection parameters, the user can set the pump injection volume, injection speed and blocking acceleration to achieve the best injection results. Production management data collection shows the number of injections to facilitate production management. Servo-driven one-way valve series pump injection range is 0-20 ml, independent of pressure fluctuations, servo-driven pump shows more stable injection performance than pneumatic pump, in the high-speed production line, can guarantee multiple pumps Filling synchronization and consistency, so that the quality of each product out of the production line is more stable and consistent.

Six, servo-driven rotary valve type (1SR/2SR) series pumps, effective metering of high viscosity liquids and liquids containing particles, injection range is 0-20 ml. Servo-driven precision screw mechanism, precision check valve control liquid input and output channels, effective measurement of low viscosity liquid infusion. Set the pump injection volume, injection speed and blocking acceleration to achieve the best injection results. The production management data collection shows the number of injections to facilitate production management (others are the same as the servo-driven check valve series pumps).
