Frac Pump Plunger Clamp

The Frac Pump Plunger Clamp is a key component to ensure the stable operation of the plunger assembly in oil and gas fracturing operations. It is mainly used to fix the connection between the fracturing pump plunger and the power end to prevent the plunger from loosening or displacement under high-pressure conditions and ensure the stability of the pump output pressure.
​
The clamp is usually made of high-strength alloy steel. After heat treatment and strengthening, it has tensile, impact, and wear resistance. It can withstand instantaneous pressure shocks of up to 10,000 psi and frequent reciprocating friction in fracturing operations. Its structural design follows the modular concept and includes a clamping body, adjusting bolts, wear-resistant bushings, and sealing components. Through precise dimensional tolerance control (generally accurate to ±0.02mm), it can achieve close cooperation with different types of plungers. ​

In terms of function, the clamp can not only quickly calibrate the concentricity of the plunger by adjusting the bolt to reduce eccentric wear, but also has a built-in self-lubricating bushing to reduce the friction coefficient of the plunger during reciprocating motion and extend the service life of the plunger and seal. In addition, some high-end models are equipped with pressure-sensing gaskets, which can monitor the change of clamping force in real time, warn of potential loosening risks through intelligent systems, and improve operational safety. ​

This component is widely used in the fracturing construction of unconventional oil and gas reservoirs such as shale gas and tight oil. It is suitable for fracturing pump equipment of mainstream brands such as Schlumberger and Halliburton. It is a core auxiliary component to ensure the continuous and efficient fracturing operation. Valve box accessories, various models, are locally stocked and interchangeable.
