Technical Specifications

Shimge BWI 1-6 Horizontal Multistage Pump

1000 GPD Reverse Osmosis System uses BWI, stainless steel horizontal multistage centrifugal pumps are non-self-priming pumps used for transporting liquid. They are classified into two kinds: cylinder type and sectional type. They adopt horizontal motor and alloy mechanical seal, which makes the replacement more convenient. The overflowing part of the horizontal process pump is made of stainless steel 304, applicable for light-corrosion medium. Relying on the high efficiency, energy-saving performance, reliable quality, wide usable range, our products receive great popularity after being launched.

Application Limits of Horizontal Centrifugal Pump

  • Temperature range of medium: Normal type 0~+68 ̊C, hot water type 0~+120 ̊C
  • Maximum ambient temperature: +40 ̊C
  • Maximum working pressure: 10 bar
  • When the density or viscosity of the transmission medium exceeds that of water, it is necessary to select a driving motor of high power.
  • pH: 6.5 to 8.5

Application Fields of Horizontal Centrifugal Pump

  • Air conditioner system
  • Aquaculture
  • Cooling System
  • Industrial cleansing
  • Environmental application
  • Water processing (Water purification) Fertilization/measuring system
  • Other special applications

Optional Available on Request

  • Full-enclosed and ventilating two-pole standard motor
  • Protection class: IP55
  • Insulation class: F
  • Standard voltage (50Hz): Single phase 220V; Three-phase: 380V or 220V

Vontron ULP21-4041 Reverse Osmosis Membrane

1000 GPD Reverse Osmosis System also uses vontron ULP21-4021 ultra low-pressure membrane delivers high permeate flows and salt rejection at lower raw water pressures, compared to regular low-pressure membrane elements. The high salt rejection and low working pressure result in up to 30% lower energy consumption compared to standard elements.

Vontron ULP 4021 series of low-pressure membrane elements are based on a 10.3 bar (150 PSI) test pressure.

Product Specifications:

  • Salt Rejection: 99%*
  • Permeate Flow: 950 gpd (3.6 m3/day)*
  • Membrane Area: 36 ft2.
  • Diameter / Length: 4 inch / 21 inch.
    *Test conditions: 1500 mg/l NaCl, 10.3 bar (150 psi), 25 °C (77 °F), pH 7.5, recovery rate 8%.
    *Pre-treatment must be used to protect the membrane (softener, antiscalant dosing pump, sand filter, carbon filter, 5 mic cartridge fitler …etc).

Vontron ULP 4021 membrane is suitable for water purification applications of water sources with salt concentrations lower than 2000 ppm, such as surface water, underground water, tap water, and municipal water.

Commercial Application of 1000GPD RO System:

  • Drinking water.
  • Softened water for homes, hotels, commercial laundries, and car wash.
  • Spot free rinse, used for window cleaning and solar panel cleaning
  • Pure water for pharmaceuticals, laboratories, Hemodialysis, and electronics
  • Sterilisers and autoclaves.
  • Chemical industry.
  • Aquarium water treatment.
  • Boiler and cooling towers make up water.
  • Pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production.

Compatible with reverse osmosis membrane types:*

Filmtec TW30-4021 / Filmtec XLE-4021 / GE Desal AG4021 / Hydranautics ESPA4-4021 / Toray CSM RE4021-BE.
*Check the datasheet for each membrane.
