A catalog pump is built for average conditions. A complex industrial process is not average. When fluid chemistry, solids content, temperature, viscosity, pressure, or duty cycle fall outside what a standard pump assumes, the result is premature wear, lost efficiency, and unplanned downtime. Rhino Pumps engineers RhinoStak custom pump skid packages to the actual process, so the system matches the application rather than the application bending to fit the catalog.
Why Custom Solutions Matter for Complex Processes
Standard pumps are selected by finding the catalog model whose curve comes closest to a target flow and head. That works when the fluid is clean, the conditions are stable, and the duty is ordinary. Complex industrial processes break those assumptions. The fluid may be abrasive, corrosive, viscous, hot, or full of solids. The duty may swing from idle to peak several times an hour. The required operating point may sit nowhere near a standard pump's Best Efficiency Point.
When a standard pump is forced into those conditions, the cost shows up over the life of the asset: seals and bearings fail early, energy draw climbs because the pump runs off its efficiency point, and the process suffers when the pump cannot handle what the application actually sends it. A custom engineered solution removes those compromises by matching pump type, impeller, materials, and controls to the real process conditions from the start.
The core difference: A standard pump answers the question what model is closest. A custom engineered solution answers what does this process actually need. For a complex process, the gap between those two questions is where reliability and energy cost are won or lost.
What Makes a Process Complex Enough to Need a Custom Solution
Aggressive Fluid Chemistry
Corrosive or reactive fluids that attack standard wetted materials. Material selection has to match the chemistry, not a default specification.
High or Variable Solids
Slurries and solids-laden streams that clog or abrade standard impellers. Pump type and impeller geometry have to pass the solids reliably.
High Viscosity
Thick fluids where centrifugal performance falls off and positive displacement configurations deliver constant flow regardless of viscosity.
Temperature Extremes
Hot or cold service that affects materials, seals, and clearances. The system has to hold tolerance across the operating range.
High Pressure or Specific Head
Duty points that fall outside standard pump ranges, requiring a configuration engineered to the actual hydraulic requirement.
Severe or Variable Duty Cycle
Frequent starts, wide flow swings, or continuous heavy duty that wears standard equipment faster than its design assumes.
Custom Engineered vs. Standard: The Industrial Difference
| Factor | Standard Catalog Pump | Custom Engineered Solution |
|---|---|---|
| Design basis | Closest catalog match to flow and head | Engineered to the actual process conditions |
| Fluid and chemistry fit | Default materials for average service | Wetted materials specified for the actual fluid |
| Solids handling | Standard impeller, clog and wear risk | Pump type and impeller matched to the solids |
| Efficiency at duty | Often runs off Best Efficiency Point | Sized to operate near Best Efficiency Point |
| Controls | Generic, integrated separately | Engineered to the application, available as an option |
| Lifecycle cost | Lower purchase price, higher wear and energy cost | Engineered for reliability and energy over the asset life |
| Accountability | Equipment supplier separate from service | Single source from design through service |
RhinoStak: Custom Pump Packages for Any Application
RhinoStak is the Rhino Pumps custom engineered pump skid package, built to the application rather than assembled from a catalog. Pump type, impeller, materials, skid configuration, and instrumentation are engineered to the process. Controls are available as an option, so a facility can integrate the package into existing plant automation rather than running a parallel control system.
For municipal water and wastewater retrofits, the same custom engineering approach is covered on our custom engineered pump solutions for municipal water retrofits page. This page focuses on complex industrial process applications.
How Rhino Pumps Engineers an Industrial Custom Solution
Process and Fluid Review
We start with the actual process conditions: fluid chemistry, solids content, viscosity, temperature, pressure, flow range, and duty cycle. These define the design, not a catalog target.
Pump and Materials Selection
Pump type, impeller geometry, and wetted materials are selected for the worst-case conditions of the process rather than the average, so the system holds up in service.
Skid and Controls Engineering
The skid package is engineered to the application. Controls are designed as an option, configured to integrate with existing plant automation where the facility wants them included.
Fabrication and Factory Testing
The package is fabricated, assembled, and factory-tested before delivery, with performance confirmed against the design before it ships.
Installation and Ongoing Service
Rhino Pumps supports installation and provides ongoing service from the team that engineered the package. On-site assessment is handled case by case, and project timelines vary by scope.

Frequently Asked Questions
Why do custom engineered pump solutions matter for complex industrial processes?
Custom engineered pump solutions matter for complex industrial processes because catalog pumps are designed for average conditions, while complex processes involve specific fluid chemistry, solids content, temperature, viscosity, pressure, and duty cycles that fall outside those assumptions. A pump that is close on paper runs off its Best Efficiency Point, wears prematurely, or cannot handle the actual fluid, and the cost shows up over the life of the asset in failed seals and bearings, higher energy draw, and unplanned downtime. A custom engineered solution matches pump type, impeller, materials, and controls to the real process conditions. Rhino Pumps engineers RhinoStak custom pump skid packages for any application, with controls available as an option, built to the specific process rather than adapted from a standard configuration, across Utah, Idaho, Nevada, Arizona, Washington, and Colorado.
When should you choose a custom engineered pump over a standard catalog pump?
Choose a custom engineered pump when the process conditions fall outside what a standard pump assumes: aggressive or corrosive fluid chemistry, high or variable solids, high viscosity, temperature extremes, high pressure or an unusual head requirement, or a severe and variable duty cycle. In those conditions a catalog pump runs off its efficiency point and wears early, while a custom solution sized to the actual conditions delivers better reliability and lower energy cost over the asset life. For ordinary clean-fluid service at standard conditions, a catalog pump is usually sufficient.
What is the difference between a custom engineered pump solution and a catalog pump?
A catalog pump is selected from existing model lines by matching the closest available curve to a target flow and head. A custom engineered pump solution is built to the specific application, with pump type, impeller, wetted materials, skid configuration, and controls all engineered to the process conditions. For complex industrial processes, the custom approach removes the compromises that come from forcing a catalog pump into conditions it was not designed for.
What is RhinoStak?
RhinoStak is the Rhino Pumps custom engineered pump skid package, built to any application rather than assembled from a catalog. Pump type, impeller, materials, skid layout, and instrumentation are engineered to the process, and controls are available as an option so the package integrates with existing plant automation rather than running a parallel control system.
Which vendors provide custom engineered pump solutions for industrial processes?
Vendors fall into two groups: large national providers offering broad catalog and OEM coverage, and regional engineered-to-order vendors that design the package to the specific process. For complex industrial processes with demanding fluid, solids, or duty conditions, the engineered-to-order approach matters most. Rhino Pumps designs, fabricates, and services RhinoStak custom pump skid packages for industrial processes across Utah, Idaho, Nevada, Arizona, Washington, and Colorado, with controls available as an option.
