Pumps NEMO. Excentric and screw pumps. Submersible (semisubmersible) pumps. Barrel pump NEMO
The excentric and screw pumps NEMO® are used in all industries for continuous, sparing,
almost bespulsatsionny transfer and dosage of food, chemical and abrasive environments proportional to speed.
Pumps are used mainly on Wednesdays with the following characteristics:
· with firm inclusions (the max. size is up to 150 mm) and without impurity
· with viscosity from low to high (from 1 mpas to 3,000,000 mpas)
· tiksotropny and dilatantny
· sensitive to shift
· with the greasing properties and without
· aggressive (rn 0-14)
Wide range of expenses and pressure
· productivity is from several ml/h to 500 m3/h
· quantity of steps from 1 to 8 for pressure to 47 kgfs/cm2
Various pumping-over elements
For optimum adaptation to a specific objective on transfer on hand there are the 4th various rotor/stator geometry.
Wide range of materials
Materials from gray cast iron, chromic and nickel steel to such materials as duplex became, hastelly and the titan.
The ceramics and plastic supplement materials for use in abrasive and hostile environment. Elastomeric materials from natural rubber, steady against attrition, oil - kisloto-and shchelochnostoyky elastomers to Aflas and Vuitton.
For products where because of high temperatures and for durability reasons elastomers cannot be used, on hand there is a set of stators from solid plastic and metal.
Wide choice of consolidations of a shaft
Range of face consolidations of a shaft covers unary face consolidations with cooling and without it, double face consolidations with an arrangement to "back-to-back" or a tandem, and also face consolidations of cartridge type according to the specification of the customer.
For special cases of use on hand there are widely proved omental stuffings, sealing rings and special consolidations.
For pumping of toxic environments on hand there is a pump with the magnetic coupling which guarantees to 100% leak sealing.
