Pump Carts

Our sanitary carts are available with Alfa Laval or Ampco centrifugal pumps and a NEMA 4X variable VFD.

Centrifugal

Chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering.

Rotary Lobe

Best used for pumping slurries, pastes, and many other viscous liquids. Ideal for fluids that contain small to medium size particulates.

Circumferential Piston

Useful for processes that feature low viscosity and high pressure. Useful for generating medium to high system pressure.

Air Operated Double Diaphragm Pumps

Used for transfer applications handling a variety of feeds including abrasive and shear sensitive fluids. Limited to low pressure applications.

Twin Screw

Suited for gentle handling and low pulsation pumping. Capable of delivering process and then CIP with one pump.

Electric Motors

As a stocking distributor of Sterling Electric pump motors we have the right horsepower & speed in-stock and ready to ship.

Eccentric Disc

Seal-less design is ideal for food processing that requires sanitary operating conditions. Provides low shear, no leakage, and reduced maintenance.

Mixing and Blending

We offer liquid mixing and shear blending to ensure you have the system you need.

Drum Pumps

Engineered to disperse, meter, or remove product from drums, totes, tanks, and kettles.

How Our Pumps Work

The exact way a pump functions depends on its type. Most pumps, like centrifugal pumps, move lightweight and dense liquids by funneling the material through tubes using a motor. Other pumps, like twin screws, rely on energy generated from movement on the screws.

Features and Benefits of Our Pumps

For any industry that manufactures liquid for human consumption, sanitation is key. Incorporating pumps made out of high-quality stainless steel into your systems helps. After all, this material can withstand exposure from most cleaning agents and materials without forming dents that harbor bacteria. Many of our products use 316L stainless steel to manufacture the pump because of its strength and resistance to corrosion. In addition to superior material makeup, each of our pump types contain unique features and benefits.

Types of Pumps - How They Work & Applications

Centrifugal Pumps

Centrifugal pumps possess high flow rate capabilities, which is why they are one of the most popular types of pumps. They rely on movement from a motor to transport large quantities of fluids, typically water-like, through liquid passageways. These pumps work well in the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries.

Rotary Lobe Pumps

Rotary lobes are excellent for transporting thick, sticky fluids, like pastes. Liquids move through the interior casing thanks to energy generated by two rotating lobes. These lobes are able to push fluids forward quickly without damaging them. Rotary lobes function well in the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries.

Circumferential Piston Pumps

Circumferential piston pumps best suit low-viscosity liquids. These pumps rely on energy generated by two rotors pushing liquids forward. They can feature a stainless steel gear case, which prevents rusting, chipping, and peeling. Our manufacturers design these systems for the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries.

Air-Operated Double Diaphragm Pumps

Air-operated double diaphragm pumps are versatile pumps. They can safely handle both abrasive and shear-sensitive liquids. However, these pumps are limited to low-pressure applications. Air-operated double diaphragm pumps feature two interior diaphragms that move back and forth to pump liquids through. Our manufacturers design these systems with the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries in mind.

Twin Screw Pumps

Known as a gentle pump, a twin screw pump carefully handles liquids with low pulsation pumping. Twin screw pumps work by quickly rotating two interior cylindrical screws, which generates energy that pushes liquids forward. These pumps work well in the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries.

Eccentric Disc Pumps

Many people love eccentric disc pumps for their seal-less and low-maintenance qualities. They include a disc on an off-center shaft that rotate, producing enough energy to push liquids forward. These pumps work well in the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries.

Mixers and Blenders

Mixers and Blenders feature a high-speed rotor with rows of rectangular shear teeth. For the ones that also pump, the movement generates energy that propels liquids through passageways. As a side bonus, these machines also blend different liquids together evenly. Mixers and blenders function well in the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries.

Drum Pumps

Drum pumps can both distribute and remove low viscosity liquids, like juice or soda. While simple in their design, our typical drum pump features a high-tech metering system that ensures accurate performance. Electrically operated drum pumps get their energy from a small motor that connects to a shaft and pumping element. Drum pumps best suit the food, dairy, beverage, brewery, home and personal care, pharmaceutical, biotech, and chemical industries.
