The Sydex advantage - 2 Year Warranty!

The pin joint system is critical to any progressing cavity pump, and therefore the more robust and reliable the better. The Sydex pin joint system has been specifically designed to ensure extremely long service life. Firstly, by maximising the length of the coupling rod, we have ensured that the angular motion is kept to a minimum [less than 0.5 degrees]. Simply put, the less the angular motion, the less the forces and loads on the rotor end, and the pump drive shaft. This significantly extends stator life, and ensures the mechanical seal is not adversely affected by shaft deflection. Many of our K range  use a  4 pin joint system,  unlike our competitors who use only 2. By using this system, we are able to supply the coupling rod as a complete pre-assembled kit, making assembly and maintenance a simple task. The pin joint is securely sealed with an elastomer cover, and protected by a metallic sleeve.The joint is oil-lubricated ensure excellent heat dissipation. We are so confident in our design, that we will provide a 2 year warranty on the pin joint system [terms and conditions apply].
