Graco Industrial Pumps for Mining: SoloTech Peristaltic and QUANTM Electric Diaphragm
Graco Inc. manufactures multiple equipment lines. This LibertyCES page is scoped specifically to Graco's industrial fluid-transfer pumps for selected mining duties: SoloTech peristaltic hose pumps and QUANTM electric double diaphragm pumps.
Graco's Industrial Fluid-Transfer Pump Line
Graco Inc. serves several markets, including contractor and homeowner spraying equipment as well as industrial manufacturing and fluid-handling systems. The products covered here are part of the industrial fluid-transfer side of Graco's business. This page does not cover caulk guns, paint sprayers, or other spraying equipment.
For mining and mineral-processing duties, LibertyCES focuses this manufacturer pillar on two distinct Graco pump families. SoloTech addresses selected low-flow dosing, abrasive slurry, and caustic transfer duties through a hose-isolated peristaltic design. QUANTM addresses selected AODD replacement, dewatering, transfer, and remote-control duties through an electrically driven double-diaphragm design.
Capability-Based Mining Fit
Mining use on this page is based on documented pump capabilities and application conditions. Exact suitability still depends on fluid chemistry, concentration, temperature, solids, viscosity, flow, pressure, duty cycle, and the selected configuration.
Two Different Primary Failure Modes
SoloTech removes dynamic process shaft seals and wetted check valves from the fluid path. QUANTM removes the compressed-air requirement while retaining diaphragm isolation and controllable electric operation.
SoloTech and QUANTM Serve Different Primary Mining Duties
These pumps overlap in some transfer applications, but they should not be treated as interchangeable. Start with the duty's dominant failure mechanism and then verify the exact product configuration.
Primary Fit: Reagent Dosing and Abrasive Slurry Transfer
SoloTech uses a single roller to compress an engineered hose through a full rotation. The process fluid remains inside the hose, so the fluid path does not include a dynamic process shaft seal or wetted check valves. Graco describes the family for caustic, abrasive, or sensitive materials used in metering and transfer.
Key differentiator: the hose isolates the process fluid from the pump casing and removes two common wear or plugging points from abrasive and caustic service.
- Precision reagent dosing where repeatable low-flow control is required
- Abrasive lime slurry or selected solids-bearing chemical transfer
- Caustic chemical metering when the hose and barb materials are compatible
- Reversible line clearing when the process design permits reverse operation
Primary Fit: AODD Replacement, Dewatering, and Remote Service
QUANTM is an electric double diaphragm pump designed to provide the operating behavior of a diaphragm pump without requiring compressed air. Graco states that qualifying installations can reduce energy usage and cost by up to 80% compared with pneumatic pumps. Integrated I/O supports remote operation and speed control.
Key differentiator: QUANTM replaces the compressed-air power train with an electric drive while preserving diaphragm isolation, stall-under-pressure behavior, and configurable process control.
- Replacement of pneumatic AODD pumps where compressed-air cost or access is a problem
- General dewatering and transfer within the selected model's pressure and solids limits
- Remote-control or automated service using integrated I/O
- Remote or solar-supported installations using a correctly engineered power and inverter package for the selected configuration
Primary Fit, Not a Rigid Yes-or-No Matrix
Both product families can overlap in transfer and dispensing duties. The matrix below preserves the campaign's primary-fit logic while making the conditional areas explicit.
Screening rule: this table identifies the technology to investigate first. It does not approve a final pump model, chemical compatibility, solids passage, voltage, or operating point.
| Application | SoloTech | QUANTM |
|---|---|---|
| Precision reagent dosing | Primary fit | Conditional QUANTM can meter or dispense, but SoloTech is the low-flow precision default. |
| Abrasive slurry transfer | Primary fit | Model-dependent Solids capacity varies by i30, i80, i120, and i120LP configuration. |
| AODD replacement | Not typical | Primary fit |
| General dewatering | Limited / conditional | Primary fit |
| Remote or solar-supported service | Not manufacturer-promoted | Documented capability Selected systems may be supplied from 12/24 VDC sources through a correctly sized inverter and protection package. |
Always confirm the exact pump model, fluid-section materials, hose or diaphragm materials, connection size, pressure limit, solids allowance, voltage, hazardous-location requirements, and control method before quotation.
How to Choose Between SoloTech and QUANTM
Start with the process duty rather than the brand name or maximum flow number.
Define the Actual Service
Record chemical, concentration, temperature, required flow and pressure, specific gravity, viscosity, solids size and concentration, suction conditions, and duty cycle.
Identify the Dominant Failure Mode
Use SoloTech as the primary review path when abrasive or caustic fluid is attacking seals or check valves and low-flow dosing matters. Use QUANTM when compressed air, AODD operating cost, dewatering, or remote control is the main problem.
Verify the Exact Configuration
Match the selected family to the real hydraulic point and complete wetted path. Manufacturer charts are screening tools; final approval requires current model data and project-specific compatibility review.
Send LibertyCES the real service conditions: chemical and concentration, temperature, flow, discharge pressure or head, suction conditions, viscosity, solids, duty cycle, available power, hazardous classification, desired controls, and current pump failure history.

What is the difference between SoloTech and QUANTM for mining service?
SoloTech is a peristaltic hose pump whose primary fit is precision reagent dosing and selected abrasive slurry transfer because the fluid stays inside the hose and does not contact a dynamic process shaft seal or wetted check valves. QUANTM is an electric double diaphragm pump whose primary fit is AODD replacement, general dewatering, transfer, and remote-control service without compressed air.
Which Graco pump is the primary fit for precision reagent dosing?
SoloTech is the primary low-flow precision default in this campaign. QUANTM can meter or dispense in qualifying applications, but the required flow range, pulsation tolerance, pressure, fluid properties, and control accuracy must be checked before treating it as a dosing pump.
Can QUANTM replace an air-operated double diaphragm pump?
QUANTM is designed as an electric alternative to pneumatic diaphragm pumps and does not require compressed air. Graco states energy usage and cost reductions of up to 80% compared with pneumatic pumps in qualifying installations. The replacement still requires verification of the operating point, solids, fluid-section materials, voltage, hazardous-location rating, and controls.
Can QUANTM be used at remote or solar-supported mining sites?
Selected QUANTM configurations can support remote operation and can be integrated into engineered battery or solar-supported power systems through an appropriately sized inverter and electrical protection package. This is configuration-dependent and should not be treated as a universal direct-solar rating for every QUANTM model.
