CHARLOTTE, NC. — SPX FLOW’s APV brand introduced its new APV DW+ Positive Displacement Pump, the latest addition to its DW series. Designed to optimize the processing of high-value, high-viscosity products, the DW+ pump portfolio offers 27 different models and serves many industries, including food and beverage, personal care, pet food and more.

The APV DW+ pump’s pulsation-free, low-shear design protects downstream equipment by minimizing vibration, noise and pressure surges. By doing this, it maximizes operational efficiency, reduces downtime and safeguards product integrity, according to SPX FLOW. 

“We are proud to launch the latest innovation from APV, the DW+ pump, as the next generation of the trusted DW Series, which has delivered reliable performance worldwide for decades,” said Jet Liu, global product manager of nutrition and health hygienic pumps. “It is engineered to meet the evolving needs of modern processing operations. We are proud to introduce this proven and continuously evolving pump technology to the market so customers can experience its value and benefit from APV’s legacy of flexibility, quality and reliability.”

The APV DW+ pump offers:

  • Pulsation-Free Operation, which regulates flow with a unique piston rotor design, reducing vibration, noise and pressure surges to protect downstream equipment and enhance operational stability.
  • Versatile Configuration, which offers flexible processing with interchangeable piston or bi-lobe rotors for pumping different types of fluids, along with optional features, such as a rectangular inlet and thermal jacket, catering to specialized applications.
  • Integrated Pressure Relief Valve, which enhances safety by automatically releasing excess pressure, reducing the need for additional pressure-regulating devices and minimizing maintenance costs.
  • Energy-Efficient Performance, which reduces energy consumption through its minimal internal clearance design, allowing the use of smaller, more efficient motors, which leads to cost savings.
  • Gentle Product Handling, which minimizes shear stress due to the long sealing path of the piston rotor, preserving the texture, viscosity and sensory attributes of high-value, sensitive products.
