Manual Pump

Manual Lubrication Pumps:
In conventional lubrication systems, manual lubrication pumps differ from grease guns mainly in the viscosity of the lubricants, allowing for the use of from oil to the soft grease. Typically, manual lubrication pumps use a piston structure with separate check valves for oil intake and output. Their cylinders are usually made of zinc alloy, requiring high airtightness. Manual pumps are characterized by easy installation, simple structure, cost-effectiveness, and no operational restrictions.
