Graco Diaphragm Pumps for Industrial, Process and Hygienic Fluid Transfer
Graco diaphragm pumps cover a wide range of industrial, process and hygienic fluid transfer applications. Whether you’re moving chemicals, abrasive or solids-containing fluids, viscous products or sensitive ingredients, the right pump can provide reliable transfer with practical maintenance and a choice of materials to suit the fluid.
MacEwans can help you match a pump to your fluid, required flow and pressure, viscosity, solids content, hygiene and cleaning requirements, suction conditions, and the air or electrical supply available on site.
| Pump type | Drive type | Best suited to | Key strengths |
|---|---|---|---|
| Husky Air Operated Double Diaphragm Pumps | Compressed air | Industrial fluid transfer, chemical transfer, abrasive liquids, viscous fluids and solids-containing fluids | Broad material options, dry-run capability, pressure-safe operation and larger solids handling on selected models |
| QUANTM Electric Double Diaphragm Pumps | Electric drive | Sites wanting lower compressed air demand, quieter operation, energy savings and process control | No compressed air required, integrated controls, remote operation capability and flow rates up to 450 lpm depending on model |
| SaniForce Hygienic Double Diaphragm Pumps | Air-operated and electric options | Food, beverage, personal care, pharmaceutical and ingredient transfer | Hygienic construction, tri-clamp connections, cleanability, gentle transfer options and selected CIP/COP capability |
Common Graco Pump Applications
Graco pumps can be used across a range of industrial, process and hygienic transfer duties. The right pump depends on the product being transferred, the site setup and the level of control, cleanability or solids handling required.
Husky air operated double diaphragm pumps are suited to industrial transfer applications where compressed air is available and a rugged, flexible pump is required. They are commonly used for process fluids, chemical transfer, abrasive liquids, viscous materials and fluids containing solids.
The Husky range includes a wide selection of pump sizes and material options, allowing the wetted parts to be matched to the fluid being transferred. Depending on the model, Husky pumps can achieve flow rates up to 1,135 lpm, fluid pressures up to 8.6 bar and solids handling up to 46mm.
Key points:
QUANTM electric double diaphragm pumps are designed for applications where electric operation, lower energy use, quieter running and greater control are important. They offer many of the practical operating benefits of diaphragm pump technology while removing the need for compressed air during normal operation.
The QUANTM range includes i30, i80 and i120 industrial models. Depending on the model, these pumps provide flow rates up to 450 lpm, with 240V single-phase power and material options including aluminium, polypropylene, conductive polypropylene, stainless steel, cast iron, Hastelloy and PVDF.
Key points:
SaniForce hygienic double diaphragm pumps are designed for low to medium viscosity ingredient transfer where cleanability, product integrity and sanitary construction are important. They are suited to food, beverage, personal care and pharmaceutical applications, with air-operated and electric options available across selected ranges.
The range includes hygienic pump options for beverage transfer, food-grade transfer, high sanitation, 3A approved applications, large particle transfer and pharmaceutical use. Depending on the model, SaniForce pumps can support tri-clamp fluid connections, CIP or COP cleaning procedures, stainless steel hygienic construction, low-shear transfer and flow rates up to 870 lpm.
Key points:
Graco diaphragm pumps are used for transferring industrial, process and hygienic fluids. Depending on the pump type and materials selected, they can be used for chemicals, abrasive liquids, viscous products, solids-containing fluids and sensitive ingredients.
Useful information includes the fluid being pumped, flow rate, pressure, viscosity, temperature, solids size, chemical compatibility, suction conditions, available compressed air or power, and any hygiene or cleaning requirements.
Air-operated pumps run from compressed air, while electric diaphragm pumps use an electric drive. The right option depends on site utilities, energy goals, control needs and operating environment.
A hygienic pump is used when the product needs sanitary handling, cleanability or gentle transfer. This can apply to food, beverage, personal care, pharmaceutical and ingredient transfer applications.
Yes. Selected material options can be matched to corrosive fluids. The right construction depends on the chemical, concentration, temperature and operating conditions.
Yes. Selected models can handle solids. The correct pump depends on the particle size, fluid type and whether the product needs gentle handling.
No. QUANTM pumps use an electric drive and do not require compressed air for normal operation.
Yes. Graco double diaphragm pumps are designed to tolerate dry running, which can help reduce pump damage when fluid supply is interrupted.
Leak detection can help identify diaphragm rupture or product leakage earlier, supporting maintenance planning and reducing the risk of unnoticed product loss.
Yes. Pulsation dampeners can be used in selected systems to help reduce pulsation, noise, plumbing stress and product disturbance.
