Hydraulic grease pump Stream

electricpistonfollower plate

Overview
The BEKA Stream is designed for large industrial applications that require a high lubricant volume and is compatible with EP greases up to NLGI-2. The unit supports use in single-line, dual-line or progressive lubrication systems and is available in electric and hydraulic drive options.

General
The Stream can be supplied with various reservoir sizes (41, 54, 68 L containers or a 213 L barrel). A follower plate with an intelligent follower-piston contour prevents air ingress into the container, ensures full use of the grease and reduces oxidation. Optional fill-level monitors enable planned refilling. The system operates at relatively low pressure to avoid grease separation. When configured for progressive lubrication, the pump can be controlled by the external Tronic-E control unit, which stores settings and statistics.
