DYNEX PF1300 now in stainless steel edition

Dynex has expanded the PF1300 series with a stainless steel variant. With the PF1300-20, customers have greater flexibility in material selection and better ability to adapt the pump solution to both corrosive offshore environments and more cost-effective standard applications.

The PF1300 series is designed for critical hydraulic applications, including wellhead control systems, and for water-based fluids such as water glycol. The pumps deliver working pressures up to 15,000 psi / 1040 bar.

Flexible material choice for different needs - steel or stainless steel


In corrosive environments, typically offshore, stainless steel may be the right choice. In other applications, standard steel may be fully sufficient. This allows the solution to be adapted to the needs without over-dimensioning the material selection.

Stainless where it adds value

PF1300-20 is designed for better resistance to corrosive saltwater environments on offshore platforms. 

This makes the pump particularly relevant in installations where service life, operational reliability and reduced maintenance requirements are important.  

At the same time, stainless steel is not necessarily required in all systems. When using glycol-based fluids, there is no automatic need for a stainless steel design. This is precisely why the flexibility of the PF1300 series is so important.

An established platform for demanding applications

The PF1300 builds on an established pump platform for applications where reliability is critical. The series is well-suited for use in wellhead control systems both onshore and offshore, as well as other critical hydraulic functions.

DYNEX pumps are known for compact design, high-pressure capabilities and robust solutions for demanding operations. This makes the PF1300 series a good choice where both performance and reliability are important.

Why DYNEX? 

The DYNEX pumps are based on a robust Checkball design, developed for high wear resistance and high volumetric efficiency, even with liquids with low lubricity. The construction of the pumps contributes to lower internal load, lower starting torque and longer pump life. In addition, the DYNEX pumps are developed for water glycol, maintenance-friendly design, reduced size, weight and cost, as well as ATEX compatibility.  

You thus get a solution that combines: 

  • high-pressure properties up to 1040 bar  
  • compact design  
  • operational reliability in critical applications  
  • flexibility in material selection  
  • opportunity for cost optimization
