Prime now offers Graco diaphragm pumps for industrial and process applications where fluid characteristics or operating conditions make pump selection more demanding.
Corrosive chemicals, viscous products, suspended solids and intermittent fluid supply can contribute to wear, clogging, compatibility issues or unreliable flow when the pump is poorly matched to the duty.
Graco’s Husky, QUANTM and SaniForce ranges give engineers air-operated and electric diaphragm pump options, including hygienic configurations – for different fluid, process and site requirements.
This blog explains where each range fits and the sizing tools, product information and manufacturer backing available through Graco. It also highlights the local selection, servicing and parts support available through Prime in New Zealand.

- Graco diaphragm pumps may be useful where chemical compatibility, viscosity, solids, intermittent fluid supply or flow control influence the pump selection.
- Husky, QUANTM and SaniForce give Prime distinct diaphragm pump options across different drive, fluid and process requirements.
- Graco’s sizing tools, product information and regional expertise help inform pump selection and ongoing support.
- Prime adds local pump advice, servicing and parts assistance.
When should you consider Graco diaphragm pumps?
Graco diaphragm pumps may be worth investigating when the fluid, operating conditions or current pump arrangement are creating issues, such as:
- Chemical compatibility – material selection becomes critical
- Viscous or shear-sensitive products – pump choice affects how the fluid is handled
- Suspended solids – clogging or wear is a recurring issue
- Intermittent supply or dry-running risk – inconsistent feed affects reliability
- Flow control or energy use – an electric diaphragm pump may offer advantages over an air-operated option.
None of these issues automatically point to a diaphragm pump. They’re reasons to reassess the pump technology, materials and configuration – and whether diaphragm technology may be a better fit.

Which Graco diaphragm pump fits the duty?
Graco’s diaphragm pump range covers different drive types and process requirements – with the best fit depending on the fluid, duty and site utilities.
Husky air-operated double diaphragm pump (AODD)
Using compressed air, the Husky AODD pump suits industrial duties involving chemicals, viscous fluids and suspended solids. It’s a practical option when dry-run tolerance and operating flexibility are important and an air supply is already available.
QUANTM electric double diaphragm pump (EODD)
Driven by electricity rather than compressed air, the QUANTM EODD pump is relevant where energy efficiency, adjustable flow control or process automation are higher priorities.
SaniForce hygienic diaphragm pump
The SaniForce hygienic range is available in air-operated (AODD) and electric (EODD) configurations for food, beverage, pharmaceutical and other hygienic processes. Drive selection can be matched to available site utilities, energy efficiency objectives and process control requirements.
Across Graco’s industrial and hygienic diaphragm pump ranges, selection can be based on fluid characteristics, operating duty, control requirements and available site utilities.

FAQs about selecting Graco diaphragm pumps
Can diaphragm pumps handle fluids containing suspended solids?
Yes. Many diaphragm pumps are designed to pass suspended solids, but the allowable solids size and concentration depend on the pump model, valve arrangement and fluid characteristics. Solids size, shape and abrasiveness should all be considered when selecting the pump.
See the range of Graco diaphragm pumps in New Zealand.
How do you select wetted materials for corrosive chemicals?
All wetted components need to be compatible with the fluid – not just the pump body. Check chemical type, concentration and temperature against the materials used for the pump body, diaphragms, balls and seats before selection.
What are the practical limitations of an AODD pump?
AODD pumps rely on a compressed air supply and are generally less suited to duties where energy efficiency, precise flow control or process automation are higher priorities. The available air supply and operating requirements should therefore form part of the selection decision.
What information is needed to size and select a diaphragm pump?
Key information includes the fluid, required flow and pressure, viscosity, temperature, solids content and material compatibility requirements. Site utilities, suction conditions and the level of process control required also influence pump selection.
Talk to a Prime specialist if you’re ready to discuss the duty.
Can a diaphragm pump run dry – and what limitations apply?
Many diaphragm pumps are designed to tolerate dry running, but this shouldn’t be treated as unlimited operation without fluid. The allowable duration and operating limits depend on the pump design, speed, materials and duty – check the manufacturer’s guidance for the specific model.
