Positive displacement pump systems are widely used in New Zealand industry for controlled transfer of chemicals, additives, and higher-viscosity process fluids. Through John Morris Group, customers can source proven solutions from Masterflex and Cole-Parmer, plus specialist options such as Airmac and FUTUR for AODD duties, corrosive media handling, and plant utility pumping.
Positive Displacement Pumps
Positive Displacement Pumps For NZ Chemical And Utility Workflows
Our range of Positive Displacement Pumps is designed for industrial teams that need dependable flow control and chemical compatibility in daily operation:
- Corrosive fluid handling: Airmac and Cole-Parmer pump configurations with PTFE and conductive housing options suit demanding transfer tasks in chemical processing, wastewater treatment, and industrial wash systems.
- Consistent dosing and transfer: A positive displacement pump is often chosen where operations need more predictable delivery for batching, dosing, or line feeding across process skids and production systems.
- Practical AODD integration: Masterflex and FUTUR based options support compressed-air-driven pumping where self-priming performance and simple maintenance are both important.
How to Select Positive Displacement Pumps For Your Plant
Choosing suitable Positive Displacement Pumps for NZ applications means reviewing the actual process duty, fluid chemistry, and installation layout in detail:
- Wetted materials and housing type: Review whether PTFE, polypropylene, conductive, or other material options are needed for the liquid being pumped and the site safety requirements.
- Operating profile: Check the required flow, suction lift, air supply conditions, and expected run time so the pump can deliver reliable service in real plant conditions.
- Maintenance and system fit: Consider access for servicing, spare part availability, and how the pump will integrate with the wider process line or dosing skid.
Related Pump Categories For Complete Process Design
Industrial buyers often compare or pair multiple pump types when specifying a new system. These related categories are highly relevant to the same workflow:
- Diaphragm pumps: Add or compare a pump category that is commonly selected for air-operated transfer, chemical service, and self-priming process duties.
- Gear pumps: Extend your selection review with another positive displacement technology suited to oils, additives, and controlled transfer of uniform viscous media.

Frequently Asked Questions
Are diaphragm pumps positive displacement?
Yes. Diaphragm pumps are a type of positive displacement pump because they move fluid through a repeating mechanical chamber action. They are widely used for chemical transfer, dosing, and AODD applications in industrial environments.
Are centrifugal pumps positive displacement?
No. Centrifugal pumps and positive displacement pumps operate differently. Centrifugal pumps typically vary flow more with pressure changes, while positive displacement designs are often selected when controlled transfer is more important.
Can John Morris Group supply positive displacement pumps across New Zealand for industrial facilities?
Yes. We support NZ customers with product selection, quotation assistance, and supply of positive displacement pumps, AODD systems, and related process equipment through our Auckland-based support network.
