Description

Intended for professional drill-rig maintenance in severe field conditions, the Pump Unit (OEM 551 746 40) is a compatible aftermarket component for Sandvik drill rigs and related rock-drilling equipment. The pump unit supplies lubricant to the shank and drifter lubrication points, helping maintain an oil film where rotation, impact and sliding contact generate high wear potential. Listed applications include DI 550, DP1100i and DP1500i, with additional compatible models shown in the product data.

Materials and contact surfaces are selected to handle the wear, load, vibration and repeated cycling associated with mobile drilling equipment. Reliable metering and delivery are essential for protecting the shank interface, reducing friction and supporting consistent lubrication even during long drilling cycles. Controlled dimensions support correct fit and dependable function during scheduled overhaul, wear replacement or corrective maintenance.
