Other common features for the GH include 316 SS shaft sleeves, keyed impellers to prevent accidental spin off, dynamic balancing to ISO G2.5 guidelines, and re re greaseable bearings secured with locking rings, as standard. These features combine to produce shaft deflection values so low that they exceed the requirements of ANSI B73.1M-1991 and overall, provide some of the most efficient hydraulics in the industry.

Options for the JP include replaceable wear rings, cartridge seals, and flush plans. Along with these, higher alloy material options such as Ni-Al-Br and CD4MCuN and a full range of motor and baseplate choices are also available.

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.

‍

Capacities range to 1000 GPM, depending on discharge head and speed of operation. Available in 6 sizes ranging from 1”-4”; standard materials of construction include All Iron, CD4MCu and Rubber Lined. The 855Series features an overhead v-belt drive arrangement as a standard, with options for close coupled or frame mounted drives. By utilizing either belt drive or variable frequency drive, performance characteristics can be fine-tuned to match most system requirements. Maintenance is simplified as the vertically split case maybe disassembled to expose the entire wetted area. Standard features include a rotatable discharge casing which allows flexibility in locating desired discharge flange orientation, packed stuffing box with seal water connections provided to insure lubrication and eliminate vacuum/air leakage and 2” diameter stuffing box bore on all units. Pumps come with discharge flanges dual drilled for both 150lb / PN 10 connections. 17-4pHstainless steel shafts are utilized to both strengthen the shaft and eliminate the need for shaft sleeves (duplex shafts with CD4MCu). Impellers are keyed to the shaft ,providing a secure fit and protection should momentary reverse rotation occur. The Swing-Out Mount is popular as an optional feature, allowing inspection of the pump or quick access to the tank interior.

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 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.

Petrochemicals generate starting products for the manufacture of plastics, pharmaceuticals, colorants, detergents, and other products. The most important operations are the various splitting or cracking processes (e.g. steam cracking, hydrocracking). These processes convert long-chained hydrocarbons (e.g., naphtha) into short-chained ones.
