For over 50 years, oil-flooded rotary screw compressors have been the workhorse of modern industry. Blackhawk Equipment partners with Sullair to deliver solutions that go beyond basic air compression. Our units feature US-engineered rotors and optimized air ends designed to lower your kW/cfm ratio—delivering maximum air power with minimum energy consumption.
Whether for general manufacturing, automotive, or heavy-duty industrial applications, our oil-flooded systems offer a maintenance-friendly design and some of the quietest dBA ratings on the market.
Standard on most models for long-term peace of mind.
10,000-hour non-varnishing, biodegradable fluid life.
Time-proven Sullair air end technology for superior longevity.
The Grundfos TP and TPE series are robust, single-stage, close-coupled centrifugal pumps designed for a wide variety of heating, cooling, and district energy applications. Available with standard motors (TP) or ultra-efficient speed-controlled motors (TPE), these in-line pumps offer a compact mechanical shaft seal design that simplifies maintenance and installation.
The Grundfos CR series is the world’s most versatile vertical multistage centrifugal pump, known for its reliability in high-pressure boosting applications. With suction and discharge ports on the same level (in-line), these pumps are easily installed in complex piping systems and are available in various material grades to handle water, chemicals, and oils.
Grundfos SP pumps are renowned for their high efficiency and resistance to sand and other abrasives. Constructed entirely from corrosion-resistant stainless steel, these submersible pumps are the industry standard for groundwater supply, irrigation, and dewatering in boreholes ranging from 4″ to 10″ in diameter.
The Grundfos S-Series offers a range of heavy-duty enclosed centrifugal pumps designed for the transfer of raw sewage and wastewater. Featuring free-flow channel impellers or SuperVortex impellers, these pumps are engineered to handle large solids without clogging, suitable for both submerged and dry installations.
Grundfos dosing pumps deliver high-precision chemical injection for flocculation, disinfection, and pH adjustment. Utilizing advanced stepper motor technology, these mechanical diaphragm pumps provide a massive turndown ratio and smooth continuous flow, ensuring process stability in water treatment applications.
For the most extreme environments involving toxic, corrosive, or aggressive liquids, Grundfos offers the CRT and ANSI process series. The CRT models feature wetted parts made of Titanium, offering exceptional resistance to acids, alkalis, and seawater where stainless steel would fail.
Designed specifically for mounting on top of tanks, the MTR and SPK series are vertical multistage centrifugal pumps ideal for machine tool coolants, parts washers, and condensate return systems. The pump hydraulic assembly is immersed in the liquid while the motor remains air-cooled above the tank.
For high-flow applications, the Grundfos LS (Horizontal) and LSV (Vertical) split case pumps offer a robust solution with high efficiency. Their split-casing design allows for easy access to rotating components without disturbing the piping or driver, making them ideal for large-scale municipal and industrial distribution.
Modern pump efficiency relies on intelligent control. Grundfos Communication Interface Modules (CIM) and Control Units (CU) enable seamless integration of pumps into Building Management Systems (BMS) and SCADA networks.
A compressor is only the heart of the system. Protect your downstream equipment and ensure ISO 8573-1 compliance with our matched air treatment, storage, and distribution solutions.
