Delivers precise, multi-point lubrication for heavy-duty industrial equipment using a reliable mechanical box system.
The Graco MBD1HJ Lubricator, Manzel, Box, Gbl is a high-performance mechanical box lubricator from the Manzel MB series, designed to deliver precise and consistent oil distribution to critical machine components. Built with durable materials and engineered for reliability, this lubricator is widely used in heavy-duty industrial environments where continuous lubrication is essential.
This unit operates using a cam-driven mechanism with internal gear reduction, allowing accurate metering of lubricant to multiple points. It supports both suction feed and force-feed lubrication, making it versatile for a range of demanding applications. The modular design enables customization using standard components, helping reduce maintenance complexity and operational costs.
Equipped with multiple pump stations and compatible with GBL 7500 pumps, the lubricator ensures controlled oil delivery under high pressure. Its robust construction and efficient design make it ideal for harsh environments such as oilfield operations and heavy industrial machinery.
