At Highland Equipment, we design, fabricate, install, and service sanitary stainless steel process equipment and systems. In addition to our complete solutions, we offer a wide range of pumps, valves, instruments, spares and replacement components for new and existing processes.

Pumps

In addition to our stainless-steel blenders and mixers, we also supply a variety of centrifugal pumps, positive displacement pumps and progressive cavity pumps. We are able to supply several different manufacturers of pumps, allowing us to provide you with the correct pump for your application. Our extensive years of expertise allow us to share knowledge with our clients for many different process requirements.

Centrifugal Pumps

Available in multistage, liquid ring, and self-priming versions, centrifugal pumps are mechanical devices that use rotational energy from their impellers to move fluids throughout the pump system. As fluid enters the chamber, the impeller’s centrifugal force imparts velocity to the fluid and drives it towards the pump outlet, facilitating quick and easy fluid transport. 

Highland Equipment offers the following Centrifugal Pumps:

  • Traditional Style Centrifugal Pumps, low viscosity
  • High Efficiency Pumps, Timing, Precision and Viscosity Control
  • Liquid Ring (CIP Return)
  • Multi-Stage high pressure (Reverse Osmosis)

Positive Displacement Pumps

Positive displacement pumps are mechanical devices that are commonly found in the food and beverage industry. They operate by trapping a fixed amount of fluid and displacing it into the pump system’s discharge pipe. Since positive displacement pumps pulsate, their flow is cyclical and not a constant stream of fluid.

Highland Equipment offers the following positive displacement pumps:

  • Rotary Lobe Pumps
  • Circumferential Piston Pumps
  • Twin Screw Pumps
  • Peristaltic Pumps

Valves

Valves are mechanical or electromechanical devices that regulate the flow of fluids (e.g., gases, liquids, fluidized solids, and slurries) by partially or fully opening and closing passages within fluid handling systems. Sanitary processing equipment requires the use of sanitary valves to remain in compliance with regulatory and industry standards. 

In contrast to standard valves, sanitary valves are engineered for use in applications with high sanitation standards, such as cosmetics manufacturing, food and beverage processing, and pharmaceutical production operations. Their design and construction are such that they minimize the risk of the entrance and/or buildup of contaminants that may affect the quality of the process and products. 

The German Food Processing Machinery and Packaging Machinery Association (VDMA) categorizes them into five classifications: Hygienic (I–III), Ultraclean (IV), and Aseptic (V). At the highest level (Aseptic), valves should feature a hermetic seal that separates the internal components from the external environment to lower the risk of contamination. Additionally, they should be able to withstand exposure to materials with a pH value of 4.5 or greater at ambient temperatures for several months. 

The sanitary valve types we supply include:

  • Air eliminator valves
  • Aseptic valves
  • Ball valves
  • Butterfly valves
  • Check valves
  • Diaphragm valves
  • Mix proof valves
  • Modulating valves
  • Plug valves
  • Pressure relief valves
  • Sample valves
  • Seat valves
  • Slide gate valves
  • Tank bottom outlet valves

Gaskets 

In processing equipment, gaskets are compressible mechanical seals that prevent fluid from leaking into or out of the mating surfaces between components. They are available in a variety of materials, shapes, and sizes, all of which should be tailored to the requirements and restrictions of the application to ensure the formation of an adequate seal. Some of the key factors to keep in mind when designing or selecting a gasket for process equipment are process material characteristics (acidic vs. basic, temperature, pressure, etc.), operating conditions and limits, curing method, and regulatory and industry requirements.      Gasket Img Example

The sanitary gaskets we provide include:

  • Tri-clamp gaskets
  • Screen gaskets
  • Orifice plate gaskets
  • I-line gaskets
  • Bevel seat gaskets
  • DIN/SMS gaskets
  • Flat face gaskets
  • Acme gaskets
  • Manway door gaskets

Fittings

Fittings are used to connect pipe, tube, and hose components and, depending on their design, influence the flow of fluid through the system. For sanitary process equipment and systems, sanitary fittings—also sometimes referred to as hygienic fittings—are vital. 

In contrast to standard fittings, sanitary fittings demonstrate superior cleanability, either by dismantling or clean-in-place (CIP) methods. They are designed and constructed to minimize the number and sizes of areas where contaminants can collect in the system and withstand the regular cleaning operations required to ensure the maintenance of sanitary conditions. Some of the common features found in sanitary fittings include: 

  • Stainless steel construction (generally 304 or 316L) or other specialty alloys such as Hastelloy or Titanium
  • Minimum surface finish quality of 32 Ra (15–25 for biopharmaceutical applications)
  • No threads, pockets, or tight radii (1.5 times the OD of the tube)

Highland can customize any fitting in the field as many piping installations are not standard, we offer several manufacturers fittings in stainless steel (304 or 316) as well as exotics such as Hastelloy or Titanium. Minimum surface finish quality of 32 Ra (15–25 for biopharmaceutical applications)

Our fitting offerings include:

  • Biopharmaceutical fittings
  • Camlock fittings
  • DIN/SMS fittings
  • I-line fittings
  • Pipe fittings
  • Sanitary ACME fittings
  • Sanitary butt weld fittings
  • Sanitary tri-clamp fittings
  • SCH5 fittings
  • Victaulic fittings
