Pneumatic Pumps Dealers in Laxmi Nagar, Rajkot

QD series pneumatic lubrication pumps are divided into QDL oil Series and QDG grease Series. This series is specially designed and manufactured to meet the market demand for high, middle and low pressure centralized lubrication systems. It is designed with compressed gas as drive source, to ensure lubrication performance of various kinds of mechanical products, to extend service life and improve precision of machinery. This pump unit is extensively used in construction machines, automotive chassis, rubber machines, forging machines and machine tools, etc. Features 1. This pneumatic lubrication pump uses automatic to and fro cylinder drive, realizing automatic reversing, and it is not necessary to connect reversal valve and program controller, etc. 2. This pump has high output pressure that can be controlled by adjusting air source pressure. The boost ratio is as high as 1:40. 3. This pump can match with float switch or proximity switch to realize low-level alarm. 4. Flexible installation modes. 5. Based on different configurations, it can be used in oil lubrication system and grease lubrication system. 1. Working principle Compression spring (1) pushes the piston (2) to the left end of the cylinder. The pull rod (3) is connected to the middle of the piston, and the pull rod causes movement of the valve core (4) to open the air inlet (5) and close the exhaust port (6). After the air inlet is opened, outside air source enters the cylinder via the air inlet for air pressure increase. The piston moves to the right and drive the pull rod to move, the air inlet closes and the exhaust port opens, and the compressed air inside the cylinder goes out from the exhaust port, and the pressure inside the cylinder drops, and the compression spring restores the piston to the left end under spring force. The to and fro motion of the piston drives the piston (7) for suction and delivery of grease. The check valve (8) in the front of the piston closes during suction and opens during grease delivery. It features simple structure and steady operation.

• Features: Robust construction.

Pneumatic (Air-powered), where compressed air is directed to the gun by hoses, the air pressure serving to force the grease through the aperture. The grease gun is charged or loaded with any of the various types of lubricants, but usually a thicker heavier type of grease is used.
