Rexroth  Axial Piston Variable Pump/ Metering Pump A7VK Description

Metering pumps, also known as metering pumps or proportional pumps, are a type of process that can meet a variety of stringent process requirements. The flow rate can be adjusted steplessly within a range of 0-100% to transport liquids, especially corrosive liquids. Special volumetric pump. The metering pump is a reciprocating positive displacement pump, used for accurate metering. It usually requires the stability of the metering pump to be no more than ±1%. With the continuous development of the modern industry towards automatic operation and long-distance automatic control, the metering pump has strong compatibility and adaptability to a wide range of media as liquid. Rexroth pump A7VK is designed for pumping polyurethane components in open and closed design.
Rexroth A7VK is a high-performance and high-precision piston pump with the following characteristics and performance: Specifications: The specifications of A7VK series piston pumps range from 12 to 107, as well as 1 and 4 series (A2VK type), suitable for various hydraulic systems. Structure: The A7VK series piston pump adopts an axial piston bent shaft structure, with open or closed circuits to provide a stable and reliable hydraulic system. This structure enables the pump to maintain stable performance and high reliability during operation. Material: The A7VK series piston pump adopts an improved high-pressure pump material, suitable for conveying polyurethane components, with high corrosion resistance and wear resistance. This material can improve the durability and service life of the pump, and reduce the frequency of maintenance and replacement. Accuracy: The A7VK series piston pump has high displacement accuracy and repeatability with adjustable output, ensuring the stability and accuracy of the hydraulic system. This precision can meet the requirements of various industrial fields for hydraulic systems, improve production efficiency and product quality. Surface treatment: The special surface treatment of the A7VK series piston pump increases corrosion protection, improves the durability and service life of the pump. This surface treatment can reduce the impact of corrosion and wear on the pump, and extend the service life of the pump. Indicator: The A7VK series piston pump is equipped with a precision measurement indicator and manual control of clamping equipment, making it easy to operate and maintain. This type of indicator can monitor the operating status and performance parameters of the pump in real time, detect and solve problems in a timely manner, and improve the operational efficiency and reliability of the pump. Seals: Double axis seals and flushing chambers made of special materials, easy to damage, inspect and protect the environment, ensuring the reliability and safety of the pump. This type of seal can reduce the impact of leakage and pollution on the environment, improve the safety and environmental friendliness of the pump. Volume efficiency: The A7VK series piston pump has high volume efficiency, which can effectively reduce energy consumption and operating costs. This volumetric efficiency can improve the efficiency and performance of the pump, reduce energy consumption and operating costs. 
Rexroth A7VK is a high-performance, highly reliable, and safe piston pump suitable for various industrial fields. When choosing, it is necessary to comprehensively consider factors such as displacement, pressure, speed, and connection method based on actual needs to ensure that a pump that suits your actual needs is selected.

In recent years, with the development of the foaming machine industry, more stringent requirements have been put forward for the performance of foaming machine pumps. In order to meet the new requirements of market development, the new generation of Rexroth A7VK metering pumps includes 12 and 28 displacement specifications. The pump adopts manual control mode. When the handwheel is rotated, the threaded rod is also rotated and the variable swash plate of the pump is adjusted steplessly, so the displacement changes in the range of small Vgmin to Vgmax. The precision adjustment display is built into the handwheel. Rexroth A7VK's curved housing design makes the structure more compact and reduces costs. The pump enhances corrosion resistance through the special surface treatment of the housing; two-way shaft seals and flushing chambers made of special materials identify hazards and protect the environment; the pump adopts a closed pump design with the same size of the high pressure port and the low pressure port, making The separation of the feed chamber and the housing allows the pump to be used in applications with a high viscosity of 5000-7000 mm2/s and a high inlet pressure of 1-30 bar. When there are special requirements for polyurethane products and high-viscosity media must be used for compounding, A7VK is an excellent choice and can solve the problem of high-viscosity and accurate ingredients that have been plaguing customers for a long time. Due to the special optimization of the structure, the A7VK emits heat quickly, which is conducive to controlling the temperature rise and ensuring the stability of the viscosity, thereby ensuring the high accuracy of the ingredient ratio. The Rexroth A7VK is an alternative to A2VK, which uses the same mounting flange and driveshaft as the A2VK, thus improving the replacement. This new metering pump has been recognized by mainstream customers in the industry. It is believed that with the promotion and use of A7VK with higher cost performance, Rexroth can better meet the requirements of more users in the foaming machine industry.
