What Are Pumps?
A pump is specified by its duty point, not by its size. Flow and head together define what the pump has to do, and a pump chosen on flow alone will either fail to overcome the system's resistance or run off its curve and destroy itself in service.
ChatMRO indexes pumps with flow rate, total head, material of construction, seal type, inlet and outlet connections, drive arrangement and fluid compatibility held as structured data. That makes "50 GPM at 120 feet of head, 316 stainless, cartridge seal" a duty point the catalogue can match directly, rather than a description to interpret.
Fluid compatibility governs everything downstream of the duty point. Abrasive slurries, viscous fluids, aggressive chemicals and anything carrying solids each rule out particular pump types outright, so ChatMRO filters on the fluid being handled before it filters on performance, narrowing to pumps that will actually survive the application.

| Spec | What It Means | Why It Matters |
|---|---|---|
| Flow Rate | The volume the pump must move per unit time, typically GPM or LPM | Undersizing flow starves the process; oversizing wastes energy and accelerates wear |
| Total Head | The total resistance the pump must overcome, combining elevation, friction and pressure | A pump chosen on flow alone without head runs off its curve and fails |
| Fluid Compatibility | The chemical, abrasive and viscosity properties of the fluid being pumped | Rules out entire pump types before performance is even considered |
| Material of Construction | Cast iron, stainless steel, bronze or engineered plastic wetted parts | Determines corrosion resistance and compatibility with the fluid and environment |
| Seal Type | Mechanical seal, packing, or magnetic drive | Governs leak tolerance, maintenance interval and suitability for hazardous fluids |

Applications
Where Pumps Get Used
The same component behaves differently by sector, because the duty cycle, the environment and the paperwork all change.
Water & wastewater treatment
Raw water intake, transfer and distribution on centrifugal pumps, with chemical dosing handled by metering pumps sized on dose rather than flow.
Chemical processing
Fluid compatibility drives everything: lined, non-metallic or high-alloy wetted parts, and double or sealless arrangements where leakage is unacceptable.
Food, beverage & dairy
Sanitary construction in 316 stainless with cleanable surface finishes and hygienic connections, so the pump can be cleaned in place.
HVAC & building services
Closed-loop circulation, condenser water and pressure boosting, where cast iron and bronze are adequate and variable speed control delivers the largest energy saving of any pumping application.
Oil, gas & fuel handling
Hazardous-area certification for motors and controls, positive displacement pumps for viscous product, and containment-focused sealing.
Mining, quarrying & slurry
Abrasion rather than corrosion sets the specification: heavy sections, high-chrome or rubber-lined wet ends and replaceable wear parts, accepting reduced efficiency in exchange for service life.
Pharmaceutical & life sciences
Low-shear, contamination-free transfer where peristaltic pumps are common because the fluid touches only the tube, making changeover and validation straightforward.
General plant maintenance
Drum and transfer pumps, portable diaphragm units and sump pumps for washdown, spill recovery and dewatering.

FAQ
Pumps Questions, Answered
Can you size a pump from my system details?
Yes. Give the flow needed, the static lift, the pipe run and the fluid, and ChatMRO calculates the duty point and returns pumps that meet it on their curve.
What pump type suits a fluid with solids?
Diaphragm, peristaltic and open-impeller centrifugal pumps handle solids to differing degrees. Describe the solids and ChatMRO recommends a type before a model.
Do you supply mechanical seals and repair kits?
Yes. Seals, impellers and wear parts are indexed against the pumps they fit, so a repair does not mean replacing the whole unit.
Can you match a pump from an old nameplate?
Yes. Give whatever is legible and ChatMRO identifies the model and its current replacement, showing where the duty point has changed.
Are chemical dosing pumps available?
Yes, indexed by fluid compatibility and dosing rate. Name the chemical and ChatMRO filters to compatible wetted materials.
