Liquid Jet Solid Pump operates on the ejector principle and serve to convey liquids with particles and flowable granular material. The motive liquid, in most cases water, emerges from the motive nozzle at a high velocity into the mixing chamber of the pump, entraining the material present in the mixing chamber. At the suction connection a feeding hopper for the solids is installed. Depending upon the type of material to be conveyed, rinse water must be sprayed into the hopper in order to maintain a constant flow.
- Simple and reliable
- Corrosion and erosion resistant
- Automatic control
- Easy to install
- Low cost
- No moving parts
- Practically no maintenance during its service if “washed down” periodically
- Convey granular solids, sand, gravel, salt, activated carbon, ion-exchange resin, absorbent carbon, chemical or pharmaceutical substances, ash, drilling mud, semisolids such as crushable foodstuff and other types of solids
- Filling and emptying reactors with reactor mass
- Adding additives to reactors
- Decarburizing and de-acidifying plants of water and effluent treatment plants
- Adding precipitating agents in dirty water and effluent water treatment
- Filling, cleaning and discharging water treatment plants
- Agricultural purposes
- Producing emulsions
- Pumping food products
- Glass industry and power production
- Maximum allowable grain diameter 8 mm
In normal operation (smooth surface grins of maximum 1.0-1.5 mm diameter without “bridging” tendency)
- Motive volume: 3 – 5 times the volume of the material to be conveyed
- Motive pressure: 2.5 – 3 times that of the delivery head.
- Rinse water: 20% the volume of the material to be conveyed
In more difficult cases (coarser materials with a rougher surface, relatively high specific gravity, tendency to form “bridges” and to bond, such as sand, ash, and sticky slurries)
- Motive volume: 5 – 10 times the volume of the material to be conveyed
- Motive pressure: 2.5 – 3 times that of the delivery head.
- Rinse water: included in motive volume consumption
- Cast iron
- Cast stainless steel
- Steel or stainless steel
- Temperature change resistant porcelain
- Other materials on request
