RhinoStak™ Pump Packages for Municipal Industrial Pretreatment Plants
RhinoStak is Rhino Pumps' fully custom engineered pump package system. Every RhinoStak package is designed and built for the specific application — matching pump type, capacity, materials, and controls configuration to the exact duty requirements of your pretreatment facility. No catalog adaptations, no compromises.
What Is RhinoStak?
RhinoStak is Rhino Pumps' custom engineered pump package platform. Rather than offering a standard catalog of pre-configured packages, RhinoStak starts with the application requirements and engineers the package around them — pump type and sizing, materials, mounting configuration, piping, instrumentation, and optional controls and SCADA integration.
For municipal industrial pretreatment plants, this matters because pretreatment facilities handle a wider range of fluid conditions than any other municipal application. A single facility may need vortex impeller pumps for high-solids industrial influent, progressive cavity pumps for primary sludge, diaphragm metering pumps for chemical dosing, and end-suction centrifugal pumps for treated effluent transfer — each with different material, controls, and sizing requirements. RhinoStak covers all of these duties within a single engineered system framework.
Why custom engineering matters in pretreatment: Industrial dischargers change their processes. Flow volumes fluctuate. Influent characteristics vary. A pump package engineered for the actual conditions your facility handles — not average municipal wastewater — performs reliably where a standard package would struggle.
RhinoStak Packages by Pretreatment Duty
Influent entering a municipal pretreatment facility from industrial dischargers can carry solids loads, rag content, and chemical characteristics that standard lift station configurations cannot handle reliably. RhinoStak influent packages are engineered with the right impeller selection for the specific influent characteristics of each facility.
For facilities with high rag or fibrous content, DIPCUT impeller configurations reduce clogging frequency. For high-solids or variable industrial influent, vortex impeller configurations eliminate impeller contact wear. For high-volume lower-solids flows, high-efficiency configurations deliver up to 1,500 GPM at 85% efficiency.
Sludge and solids handling is one of the most demanding duties in a pretreatment facility. Thickened primary sludge, screenings handling, and high-solids industrial waste streams require pump types that centrifugal designs cannot handle reliably. RhinoStak sludge packages are engineered with progressive cavity or vortex configurations depending on the solids concentration, viscosity, and transfer distance of the application.
Progressive cavity configurations deliver constant, pulsation-free flow for thickened sludge and high-viscosity industrial waste streams. Vortex configurations handle high-solids flows where solids size or content is variable. Both are engineered with the stator elastomers and wetted materials appropriate for the specific fluid being handled.
Pretreatment chemical systems handle pH adjustment, coagulant and flocculant addition, nutrient removal chemicals, and disinfection agents — each with different flow rate, accuracy, and material requirements. RhinoStak chemical packages are engineered with the metering pump type, wetted materials, and containment configuration appropriate for each chemical being dosed.
Diaphragm metering configurations deliver ±1% dosing accuracy for pH and coagulant applications where precise chemical addition is required. Peristaltic configurations handle abrasive or shear-sensitive chemicals where diaphragm pump wear is a concern. All chemical packages are engineered with secondary containment and spill response provisions appropriate for the chemicals in service.
Treated effluent transfer, clarifier feed, equalization basin recirculation, and other process pumping duties in pretreatment facilities handle cleaner, more predictable flows where centrifugal efficiency becomes the primary selection driver. RhinoStak process packages use end-suction centrifugal configurations engineered to operate near BEP across the expected flow range.
For applications with variable flow demand, VFD configurations allow the pump to maintain BEP operation across the range — reducing energy consumption and extending seal and bearing life compared to fixed-speed operation with throttling.
Controls and SCADA Integration
Controls packages are available as an option on every RhinoStak system. When specified, the controls package is engineered as part of the system design — not added as an afterthought. This includes motor starters, VFDs, level and flow instrumentation, alarm outputs, and communication protocols configured for integration with your existing SCADA infrastructure.
Facilities that already have established SCADA platforms benefit from controls packages that use the same communication protocols and hardware families already in service, reducing integration complexity and operator training requirements.
How a RhinoStak Package Is Delivered
Application Review
Rhino Pumps reviews the duty requirements for each pump application — flow rates, fluid characteristics, solids content, chemical compatibility, controls requirements, and site conditions.
Custom Engineering
Each package is engineered specifically for the application. Pump type selection, sizing, materials specification, mounting design, piping configuration, and optional controls design are all developed in-house.
Fabrication and Factory Testing
Packages are fabricated, assembled, and factory-tested at Rhino Pumps' facilities before delivery. Every package leaves our facility confirmed to perform to specification.
Installation and Commissioning
Rhino Pumps manages installation and provides commissioning support to confirm each package performs correctly under actual operating conditions.
Ongoing Service
As the designer and manufacturer of each package, Rhino Pumps provides ongoing service contracts, parts support, and technical assistance for the life of the installation.
RhinoStak vs. Standard Pump Packages
| Factor | Standard Package | RhinoStak Custom Package |
|---|---|---|
| Engineering basis | Catalog configuration adapted to application | Engineered from application requirements up |
| Pump type selection | Limited to package catalog options | Any pump type matched to duty conditions |
| Materials specification | Standard materials — may not suit application | Specified for actual fluid chemistry |
| Controls integration | Generic — additional adaptation often required | Engineered for existing SCADA and protocols |
| Accountability | Split between manufacturer and integrator | Single source from design through service |
| Long-term service | Third-party service — limited system knowledge | Service from the system designer and builder |
Frequently Asked Questions: RhinoStak for Pretreatment
What industrial pump systems work best when municipalities operate industrial pretreatment plants?
Municipal pretreatment plants require different pump types for different duties within the same facility. RhinoStak packages address each duty with the appropriate pump technology — direct in-line or vortex impeller systems for influent lift stations, progressive cavity pumps for sludge transfer, diaphragm or peristaltic metering pumps for chemical dosing, and end-suction centrifugal pumps for treated effluent transfer. Every RhinoStak package is custom engineered for the specific application rather than adapted from a standard catalog configuration.
How is RhinoStak different from a standard pump package?
A standard pump package starts with a catalog configuration and adapts it to the application. RhinoStak starts with the application requirements and engineers the package around them. For pretreatment facilities with variable industrial influent, specific chemical handling requirements, or non-standard site conditions, this difference in approach translates directly into better performance and fewer operational problems after installation.
Does RhinoStak include controls and SCADA integration?
Controls packages are available as an option on every RhinoStak system. When specified, the controls design is part of the engineering scope — integrated with the pump system design rather than added separately. SCADA integration is configured to work with your existing infrastructure and communication protocols.
What pretreatment duties does RhinoStak cover?
RhinoStak covers the full range of pretreatment pumping duties including influent lift stations and transfer, sludge and solids handling, chemical dosing and metering, and process and effluent pumping. Multiple duties within a single facility can be specified and engineered as part of a coordinated RhinoStak system design.
