Hydraulic Diaphragm Pumps

Hydraulically Actuated Diaphragm Pumps:

For more than 75 years, positive displacement, reciprocating metering pumps such as Pulsafeeder’s Pulsa Series have led the industry. Today, the API-675 compliant PulsaPro Series represents the latest technological evolution. After the largest Voice-of-the-Customer exercise in the history of the company, the PulsaPro series offers a variety of enhancements that:

  • Simplify commissioning and start up
  • Enhance the pump’s ability to survive upset conditions
  • Reduce the pump’s footprint.

PulsaPro Hypo Valve:

The Hypo Valve for the PulsaPro Pump Series and is designed to manage off-gassing in dosing applications. The Hypo Valve technology allows pressurized process fluid to cyclically flush liquid and vapors through the pump’s discharge check system, while maintaining high performance and chemical dosing accuracy. This avoids common issues, such as vapor-lock, which lead to reduced capacity and inaccurate chemical dosing while also preventing unnecessary maintenance work.

When pumping effervescent fluids, oxygen will continuously accumulate within the reagent head, significantly affecting its performance and requiring user intervention to purge the gas. The Hypo Valve features a closed loop vapor-handling system and a uniquely sealed solenoid valve that automatically evacuates trapped vapors from the reagent head.

PulsaPro Pumps, configured with the Hypo Valve, are self-priming for faster and more efficient commissioning. With the addition of this technology, the PulsaPro pump efficiently handles off-gassing chemicals such as Sodium Hypochlorite and reduces monitoring requirements and maximizes the uptime for your system.

Add reliability when pumping effervescent fluids:

  • Avoid loss of prime caused by trapped gases
  • Maintain accuracy while dosing
  • Completely integrated design with no external tubing
  • Eliminate unnecessary maintenance with automatic purging

The patented Hypo Valve design is based on proven technology that has been utilized in the field for decades by PulsaPro’s predecessors, Pulsar and Pulsar Shadow.

The Hypo Valve option is integrated directly into the PulsaPro pump – so it does not require ancillary piping or additional equipment to effectively address Sodium Hypochlorite disinfection applications.
