Product description

Sigma plunger pump – durable and high-performance

The plunger metering pump Sigma/ 2 (Basic Type) (SBKa) is a metering pump, the pump capacity of which can be precisely adjusted in 0.2% increments, either manually or optionally with an electric actuator An actuator is used to move the adjustment spindle for the stroke length adjustment of a ... more in the glossary or control drive. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification.

Sigma Basic Type Control Functions

Stroke length actuator/control drive

Actuator for automatic stroke length adjustment, actuating period approx. 1 second for 1 % stroke length, return potentiometer 1 K degree of protection IP 54.

Control drive consisting of an actuator and an integral servo controller for stroke length adjustment via a standard signal. Standard current input 0/4-20 mA corresponds to stroke length 0 - 100%. Switch-over for manual/automatic operation, key switch for stroke adjustment in manual mode, mechanical position display of actual stroke length value output 0/4-20 mA for remote display.

Variable speed motors with integrated frequency converter (identity code specification V)

Power supply 1-phase 230 V, 50/60 Hz, 0.37 kW

Externally controllable with 0/4-20 mA (see Fig. pk_2_103).

Speed controllers in metal housing (identity code specification Z)

The speed controller assembly consists of a frequency converter and a variable speed motor of 0.37 kW.
