Graco Pumps
Air-operated and electric diaphragm pumps for challenging fluids across industrial and hygienic applications.
Built for Fluids That Demand More
Graco is a strong choice where fluid compatibility, uptime, energy use and long term serviceability influence pump selection. Its air-operated (AODD) and electric double (EODD) diaphragm ranges provide the flexibility to match the drive type and pump materials to the duty.
Why Prime Partners with Graco
We choose brands that help customers keep operations running.
- Multiple Pump Technologies: AODD, EODD and hygienic options for different duties.
- Challenging Fluids: Material options for corrosive, abrasive, viscous and shear-sensitive fluids.
- Hazardous Area Options: Selected models carry hazardous area certifications (ATEX and IECEx).
- Local Support: Application advice, servicing and parts access here in New Zealand.
- Ownership Value: Serviceable designs and accessible parts support uptime and predictable lifecycle costs.

Diaphragm Pump Technology
Graco’s diaphragm pump range offers three effective options for different operating requirements:
- AODD Pumps: A practical choice where compressed air is available and dry-run tolerance, chemical compatibility or operating flexibility matter more than precise flow control.
- EODD Pumps: Electric drive adds energy efficiency, adjustable flow and process automation for dosing, chemical transfer and continuous duties.
- Hygienic Diaphragm Pumps: Seal-free, low-shear pumping with self-priming and dry-run tolerance. Air and electric drives suit different utility, efficiency and control needs.

UPTIME WHERE IT COUNTS
Reliable Flow for Difficult Fluids
Graco diaphragm pumps are chosen where compatibility, solids content, viscosity or product integrity shape the pump decision:
- Corrosive Chemicals: Wetted-material options help match the pump to acids, caustics and solvents.
- Abrasive Slurries: Diaphragm action and solids-handling options keep particle-laden fluids moving.
- Viscous Products: Positive displacement pumping helps move thicker fluids where centrifugal pump performance may fall away.
- Shear-Sensitive and Hygienic Products: Low-shear pumping protects product quality, while hygienic models support cleanability.
Overview of our Graco Pumps
Air operated double diaphragm (AODD) pumps handle challenging fluids with simple, air-powered operation. Choose for chemicals, viscous liquids, solids and shear-sensitive products. Self-priming, dry-running, easy process optimisation and maintenance.
- Max flow: 1,136 L/min
- Max pressure: 8 bar
- Max solids: 46 mm
- Stainless steel | Aluminium | PP | PVDF | PTFE
Electric Double Diaphragm (EODD) pumps combine diaphragm pump versatility with lower energy use and greater process control. Suit chemical handling, dosing and automated plant operations.
- Max flow: 454 L/min
- Max pressure: 7 bar
- Aluminium | Stainless steel | PP | PVDF
When gentle handling, self-priming and dry-running matter, hygienic double diaphragm pumps are practical. Graco SaniForce air-operated and electric pumps cover low to medium viscosity applications.
- Max flow: 870 L/min
- Max pressure: 8 bar
- Connections: 1 to 4"
- Stainless steel
- Models available: BV, FG, HS, 3A, LP and PH

Graco Diaphragm Pump FAQs
Graco diaphragm pumps transfer corrosive chemicals, particle-laden fluids, viscous products and shear-sensitive or food grade liquids. They're used across chemical processing, wastewater treatment, manufacturing, food and beverage, and other hygienic processes.
Air-operated double diaphragm (AODD) pumps use compressed air and suit duties where dry-run tolerance, chemical compatibility and operating flexibility matter more than precise flow control. Electric operated double diaphragm (EODD) pumps use an electric drive where greater energy efficiency, adjustable flow and process automation are priorities.
Yes. Graco AODD and QUANTM EODD pumps are designed to tolerate dry running – helping reduce the risk of pump damage during empty tank or interrupted supply conditions.
Yes. Wetted-material options such as polypropylene, PVDF, PTFE and stainless steel allow the pump to be matched to many acids, caustics and solvents. The correct materials depend on the fluid, concentration and temperature – and our team can help confirm compatibility for your duty.
Take a look at our range of industrial chemical pumps.
Yes. SaniForce hygienic diaphragm pumps are designed for food and beverage transfer – with stainless-steel construction, food grade material options and low-shear pumping that helps protect product integrity.
