Motor-driven pumps

Model A: Motor-driven pumps with adjustable flow 

Features and advantages

For the generation of pulsation-free and constant flow. Controlled constant volumetric flows also at minimum flow ( control range 0.2–100%). Prolonged constant flow due to large stroke capacity. Hand operation ( pulse key forward and reverse) or automatic, continuous discharge flow. Quick return to starting position and automatic reverse-to-forward motion.  Pressure generator with servo motor and integrated multiturn encoder (resolution 15 Bit). Teachable positions for reversing of movement and stroke limitations. Safety stroke limitations by inductive switches. Control box 500x 500x300 mm (h x w x d) with 5.7" TFT touch panel ( indication of actual volumetric flow and position). Supply 230 VAC/ 50 Hz. Digital interface for auto/man switch and analogue interface for set point (volumetric flow: standard configuration 4– 20 mA). Analogue output for actual volumetric flow and piston position ( standard configuration 4– 20 mA). All wetted parts in stainless steel and PTFE.

Options

Different analogue signals for external set point or actual value ( e.g. 0– 20mA or 0– 1 0 V ). Model B : With pressure control. Model C : Without controls. Opposed-piston pump ( boxer).

Model B: Motor-driven pumps with pressure control

Features and advantages

Design like model A but with pressure control function. To maintain a constant pressure in a high- pressure system. Included equipment: pressure controller, pressure transducer, hand valves and check valve ( according to flow diagram). Digital indication of piston position. Digital interface for auto/man switch and start position  as well as analogue interface for set point ( pressure : standard configuration 4– 20mA). Analogue output for actual pressure and piston position (standard configuration 4–20mA).

Option

Different analogue signals for external set point or actual value ( e.g. 0 – 20mA or 0– 10 V).

Model C: Motor-driven pumps without controls

Features and advantages

Assembled on a base plate with reduction gear box, servo motor and limit switches (an inductive limit switch on each end position). Servo motor and integrated multiturn encoder (resolution 15 Bit).

Option

Motor-mounting adapter according to the requirement of the customer.
