Small Dosing Pump

Small Dosing Pump 2 RB 10
Self-priming, rotating progressive cavity pump for the metering and dosing of small quantities. The pump is in particularly suitable for the gentle dosing and conveying of liquids of various viscosities up to pasty media. The rotation direction is reversible; the flow rate is proportional to the speed. Any parts which are in contact with the media are made of stainless steel 1.4571; there are different systems for the shaft sealing. A special advantage is the simple construction and the therefore easy cleaning and maintenance of the unit.

There are various drive systems and dosing controls for your dosing task at your disposal.
Variable speed drive with manual variator
Variable Frequency Drive
Program controlled quantity regulation for shot dosing or continuous dosing processes
Error deviations during dosing processes are influenced by various process parameters. Usually we achieve figures of less than ± 1%. The temperatures are between 0-200 °C.

Technical Data:
Flow rate: 0 - 200 l/h
Speed: 0 - 1000 Upm
Pressure up to 12 bars
Recommended drive power: 0,12 kW - 0,37 kW
Temperature up to 200 °C
Weight approx 2 kg (without drive)

Materials of Construction
Housing: 1.4571
Choice between Hastelloy, Teflon
Rotor 1.4571 hvc

Stator
EPDM, Hypalon, Perbunan, Viton, Chemrez

Joints
flexible shaft or bolt joints

Sealing
single mechanical seal, TFE Impregnated Packing Rings PTFE shaft sealing rings
Mounting on the drive: KF quick on/off clamp mounting ring

Installation:
The pump can either be driven horizontally or vertically. The housing attachment can be turned in each desired position. Therefore, almost any desired connection position is possible.

Dosing controls:
For lot metering a simple control with time or impulse parameter coding can be used. In connection with a VFD drive control this builds a freely programmable unit which can be adapted to each application. Via a digital interface, the connecting to other control or supervision units is possible, e.g., pressure control or flow meter control. However, in most cases, the pump can also be regarded as a metering unit due to its volumetrical control character. The dosing scheme for lot metering with draft back effect at the end of the dosing procedure prevents after-dripping or after-flowing of high viscous media.
Single mechanical seal with rubber bellows, ceramic / Carbon Seal Faces. PTFE impregnated packing. Double Mechanical seals with barrier fluid or quench connection upon request.

Installation:
The pump can either be driven horizontally or vertically. The housing attachment can be turned 90° in either direction. Therefore, almost any desired connection position is possible.

Dosing controls:
For lot metering a simple control with time or impulse parameter coding can be used. In connection with a VFD speed control this builds a freely programmable unit which can be adapted to each application. Via a digital interface, the pump can be connected to other controls or equipment, e.g., pressure control or flow meter control. However, in most cases, the pump can also be regarded as a metering unit due to its volumetric control character. The dosing scheme for lot metering with draft back effect at the end of the dosing procedure prevents after-dripping or after-flowing of high viscosity media.
