BASIC STRUCTURATION OF BATURIN ® SCREW PROGRESSING CAVITY PUMPS The Rotor: the external single-thread helical line with cross-section the center of which is shifted on the size of eccentricity from the rotative axis. The rotor is made of metall, coated or uncoated. The Stator: inner double threaded helical line made elastomer and fixed inside of the metal sleeve. of Articulated shaft: it transmits torque from the drive shaft to the rotor, has a high resistance to wear. The usage of transmission rod with a screw feeder is also possible. Flexible joint: it compensates eccentricity of the...

BASIC STRUCTURATION OF BATURIN ® SCREW PROGRESSING CAVITY PUMPS The main part of the single screw eccentric progressing cavity pump (PCP) is a screw pair consists of: - the stator: double threaded helical line made of an elastomer inseparably connected with the metallic casing ; - the rotor: external single thread helix line made of steel coated or uncoated. The principle of pumping is periodicall replacement of the constant volume of fluids inside the hermetic chambers between rotating rotor and static stator. While the rotor rotates, cavity from suction side increases in volume and...

BASIC ASSEMBLIES OF BN SERIES HORIZONTAL PUMPS Pump unit without bearing standwith directly mounted gearmotor Pressure up to 12 bar. Such type of the design has a compact form, more easy to assemble and maintain. Pump unit with the bearing stand design Can create a pressure more than 12 bar and up to 40 bar inclusive. Pump unit equipped with friction motor-variator Adjust performance in a wide range without reducing the reliability operation of the motor.

BASIC ASSEMBLIES OF BN SERIES HORIZONTAL PUMPS Pump unit with belt motor-variator Manual adjustment of the pump by changing the gear ratio between the electric engine and the drive shaft. Pump unit with hydraulic drive For places where is no possibility of electrical supply. Pump has relatively smaller dimensions and high level of explosion proof. The pump unit with screw feeder and hopper In case of no possibility for connecting the pipe to the inlet of the pump.

BASIC ASSEMBLIES OF BN SERIES HORIZONTAL PUMPS Pump with additional chopper-macerator Device that makes pre-crushing of clots, large hard and soft particles. Pre-disintegration and destruction device Device for pre-destruction and collapse of very viscous and pasty liquids. Pump with outlet that allows additional CIP washing Output for CIP washing is designed for automated cleaning and disinfection of the pump unit.

BASIC ASSEMBLIES OF BN SERIES HORIZONTAL PUMPS Pump with double mechanical seal accordingly Schemes of mechanical seals according to API 682 are used at Oil and Gas Industry when pumping flammable and multiphase liquids. Pump with heating system of the flow part For transfering of rapidly-solidifying and viscous liquids. Pump with «Bypass» system that protects against excessive pressure Additional protection of tubes with high pressure from overpressure.
