A7VK polyurethane metering pump for foaming machine Sizes 12, 28

Product Model: A7VK12MAORP, A7VK28MAORP

Substitute imported model: A7VKO012MA/10MRSK4P350, A7VKO028MA/10MRSL4P550

A7VK series variable piston pump for PU, using the same size as A2VK installation flange and drive shaft, so as to improve the replacement.

Compared to the A2VK series, the A7VK has a more compact design, less volume and noise, and more accurate measurement.

For high viscosity media (such as grease and polyurethane media), A7VK has a good performance.

Compared with the original imported brands, we can provide high quality products based on measure equipment and reliability equipment but at lower price. Special surface treatment ensure the good performance and quality.

1. Compact design

2. Reduced dimensions and mass in comparison to A2VK

3. Mounting flange, drive shaft and functions identical to A2VK, thus easy to replace

4. Manual adjustment with prescision display and clamp unit to prevent accidental adjustment

5. Double shaft sealing made of special material and flushing chamber to identify damage and protect environment

6. Improved volumetric efficiency through robust rotary group using proven axial tapered piston technology

7. Optionally available with mounted high-pressure relief valve

It is used for conveying synthetic monomers in a high pressure metering machine, e.g. for polyurethane processing.

Suitable for most fluids, including HLP, HFA, HFB, HFC, HFD, HFR, HFE, Isocyanates and Polyols.

High-Precision Machining: All core parts are machined by high-precision equipment, ensuring the fit accuracy and sealing performance of the pump body.
FAG Bearings: Adopting German FAG brand bearings ensures smooth rotation, low noise, and long service life.
High metering accuracy: Equipped with a high-precision adjustment indicator and handwheel made in Europe.
