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 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. 

Equipped with high efficiency valves, ductile iron pistons, self-adjusting piston rod seals and other robust features, these reciprocating gas compressors are designed to provide maximum performance and reliability under the most severe service conditions. They are also a critical component in the design of oil and gas vapor recovery units (VRUs).

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.

LEWA supports your production plants with effective additive metering, as well as with the conveying and treatment of washing water and sour water.

LEWA offers you specialized solutions for the metering and conveyance of the required chemicals and products. We design pumps and systems to suit your requirements and offer you all-round support for processes such as hydrocracking.

‍

The Nikkiso Non-Seal centrifugal canned motor pump has been designed specifically for the chemical industry. There, it is used for metering critical fluids. To do this, the centrifugal pump is designed in accordance with API 685.

LEWA is known worldwide as a specialist and market leader in the handling of supercritical fluids and the use of diaphragm metering pumps, packed plunger metering pumps and process pumps.

LEWA pumps provide high metering accuracy and are durable, reliable, safe and highly efficient.

Designed with fewer parts than competitive pumps, Graco’s air operated double diaphragm pumps features our stall-free, low pulsation air valve, which is externally accessible—ensuring rapid changeovers and minimum downtimes.

Graco’s electric double diaphragm pumps (EODD) are ideal for applications that require low pulsation and a smooth flow. Our energy efficient electric drive reduces energy consumption up to 5x compared to traditional air operated diaphragm pumps.

Each pump is ruggedly constructed to resist corrosion and deliver a long, trouble-free product life.

‍

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.

Expect a longer hose life with 360-degree single roller and only one hose compression per revolution, reducing hose wear significantly.Depending on your requirements, Graco’s industrial peristaltic pumps are available with AC and Brushless DC motor options, including motors for hazardous locations.

Our reciprocating positive displacement pumps are very inexpensive to maintain without valves, seals or glands, and easy access to maintenance point

• Efficient Pumping Action – One hose compression per revolution extends hose life
• Low Maintenance – No valves, seals or glands
• Reversible – Pumps can be used to empty lines or clear blockages
• Extended Hose Life – Only one hose compression per revolution
