Screw pumps can be applied in various sectors, including water treatment and food industries. Screw pumps are designed to pump various types of liquids: viscous, abrasive fluids, fluids with inclusions, suspensions, dispersions. Screw pump model range: D, MN, H, HS, V, X, R etc..
Where is recommended to use screw pumps?
A valvless design of the pump, direct dependence of its productivity on number of turns of the engine, and also an opportunity of change of a stream direction of a pumped liquid - all this, undoubtedly, advantages of screw pumps. Use of these features allows to recommend screw pumps for transmission of various liquids which list constantly increases. The main working part of the screw pump – pair of rotor-stator. The metal rotor of the spiral form is inside of stator (holders), made of elastomer. Under rotation of a rotor the volume of cavities inside of pair changes and the liquid moves on an axis of the pump, being superseded because of rotation of a rotor, change of volume in cavities creates soaking up effect..
- Constant non-pulsation flow on outlet.
- Proportional pumping that allows to make the pump dosing Possibility to create a high pressure
- Transferring of suspensions without structural failure and destruction of inclusions High suction capability, suction high is up to 7-8 m *
- Transferring of high viscosity liquids
- Pumping liquids with abrasive inclusions and a high content of dry substance without wear Easy maintenance
- Simple design - easy pump maintenance, low operating costs
The DN and JN Diamond series is the best solution for the industrial sector in pumping a vast range of fluids. They are synonymous with strength, reliability, performance and application flexibility.
Designed according to the most demanding standards, they comply with the requirements of standard API 676.
Suitable for pumping viscous and non-viscous products, with or without solids of any nature, they are an ideal solution for those seeking a standard product with advanced technology with unbeatable cost benefits in the current single screw pumps market.
The DN and JN series are distinguished for the type of fitting of the pump to the drive
The dosing pump with small capacities, continuous flow, low pulsations, no vibrations, very high priming and flow reversibility; is suitable to pump precisely medium liquid, dense, viscous, with solid parts on suspension.
The hopper with the feeding conveyor make pumps of this series suitable for tranfer products with high viscosity and elevated percentage of solids (up to 18%). The main usage of these pumps - sewage treatment, supply of drains on the conveyor, work on the filterpress, swapping of deposits, oil sludge and active silt. Possible versions from steel or stain- less steel.
This kind of pump can transfer sludges with high concentration of solids and the peculiar construc- tion of the hopper and the feeding conveyor is named “S” type and with this arragement it is able sometimes to substitute the bridgebreaker. In that series of pumps, it can be suggested specific technical solutions for dehydrated sludges coming from plate filter press with the 40% of dry solids. The main usages of these pumps are: work in the industry of sewage treatment, submission of drains on the conveyor, work on swapping after the filter- press.
The main usage of the pumps of series X -work in food industry. The pumps “X” series made exclusi- vely of S.S.316, have been projected and made in order to reach very high hygienic standards, removing possible dead zones, oil or grease lubricants which could damage the products. The pump construction helps the complete and easy cleaning of it; when required, it can have one or more CIP ports.
Vertical pumps in vertical execution. The vertical pumps have been projected in order to suck ea- sily the fluids from tanks, barrels, cisterns or wells and thanks to the reduced dimensions and partial immersion of the pump reduce the negative head. When requested, it is possible to supply different tank plates. Can be supplied by connectors for connections on hatches of tanks and tanks.
R Series with floating stator
Floating stator pumps have following advantages: less space and reducing maintenance costs. The stator is fixed on one single end, so as to enable the eccentric move of the rotor by means of a very simple articulation. Floating stator pump compact for use in food industry.
