For Pressures to 1,500 PSI

The RS is offered with Class 300 ANSI R.F. inlet flanges and Class 600 or 900 ANSI R.F. discharge flanges, depending on the pressures and number of stages involved. Hydraulic performance extends to 2,000 GPM and 3,400 ft. TDH, making it ideally suited for the most demanding industrial and process applications.

The RS design incorporates a product-lubricated, advanced composite material, sleeve-type radial bearing at the outboard (discharge) end. The thrust bearings are two matched angular contact ball bearings located at the inboard (suction) end of the pump. An optional outboard mechanical seal with an inboard radial ball bearing is also available. The RS has oil-lubricated ball bearings, which can be water cooled. Larger units can also be fan cooled.

The available materials of construction, from ductile iron to duplex stainless steel, offer combinations suitable for all applications from general water services to light abrasives and corrosive applications. Our proprietary advanced composite material, available for wear rings and interstage bushings, offers high-temperature performance, and exceptional resistance to wear and corrosion.

The 1000 Series is based on the proven internal gear principal and is enhanced in response from our OEM customers for a pump that offers advanced features which make installation easier. These side-ported pumps have the option to bolt SAE/DIN flanges onto them ensuring maximum flexibility on the porting arrangements. Our pump meets your technical requirements and is easily fitted into your system. Our manufacturing expertise and knowledge of applications enable us to provide you with an engineered solution and ensure satisfaction with post-sales service. We pride ourselves on properly servicing you with specification, installation, operation, and troubleshooting.  The pump was originally designed to meet and exceed the exacting requirements of the refrigeration compressor market.

Engineered to control, measure and dispense preset volumes of liquid from drums, IBC’s, plating tanks or any large storage vessel. The air systems are ideal for high frequency, continuous duty applications. The BCS can be used in an industry where batching, chemical packaging or dilution is required to be accurate and efficient. Simply dial in the desired volume, press ENTER and the BCS delivers a preset volume of liquid virtually hands-free.

The regenerative turbine pump design is very unique and works on a different principle than PD pumps. The impeller is a rotating, non-contacting, free-wheeling disc which has many small buckets or cells (typically about 60) on its periphery. When liquid enters the suction port it is picked up by the impeller and instantly accelerated around in the narrow hydraulic channel (casing volute) surrounding the cells. Kinetic energy is imparted to the liquid being flung outwards by the centrifugal force from the liquid in the teeth cells, while circulating radially around the channel. 

The simplest type of centrifugal pump is the single stage machine that consists fundamentally of a rotating element, called an impeller, and a casing. Liquid is led to the eye or center of the impeller and is set into rotation by the impeller vanes. By virtue of centrifugal force the liquid is thrown from the rim or periphery of the impeller with a considerable velocity and pressure. The casing, which closely surrounds the impeller, has a volute shaped passage of increasing area, which collects the liquid leaving the impeller, and converts a portion of its velocity energy into additional pressure energy. This casing passage leads to the discharge nozzle of the pump where it is forced into the discharge piping.

The Graco diaphragm pumps come in a wide range of air operated and electric diaphragm pumps (ATEX models available). You can also choose from a extensive selection of materials to handle numerous applications, including corrosive and abrasive fluid transfer.

Graco portable food-grade double diaphragm pumps offer food processors flow rates that are at least 25% greater than many competitive pumps. Higher flow rates give you the flexibility to process more food products, ranging from low to medium viscosity fluids. Additionally, Graco's class-leading dependable diaphragm pumps offer a wide range of food-grade elastomers including Santoprene, PTFE and overmolded EPDM/PTFE.

For maximum sanitary safety, all fluid contact materials in our sanitary double diaphragm pumps also comply with FDA regulations, including the U.S. Code of Federal Regulations (CFR) Title 21.
