Ogura mobile pump clutches are electromagnetic clutches that mount directly onto a hydraulic pump, water pump, or air compressor. We call them mobile clutches because they are used on equipment that moves, like trucks or ships for example. Except for larger pumps that are inline arrangements, the largest volume of clutches produced by Ogura are for belt driven systems. It is common for the pump to be located near an engine or PTO shaft. These are often underhood applications on tow trucks, service vans, ambulances, snowplows, construction equipment, and utility trucks, but can also be for ice resurfacing equipment or commercial fishing vessels, as an example.

Ogura has been making mobile clutches for decades and has produced well over three hundred million clutches. We support about one-third of the world's market share for air conditioning compressor clutches for automobiles. Making quality parts at a fair price is critical. Over the years, Ogura has invested heavily in the unique capital equipment needed to make these products efficiently and affordably. Also, the strength of the supply chain helps Ogura offer the best quality, consistency, and price. The clutches used on the smaller volume pumps and compressors applications are built with the same equipment and supply chain. The process is streamlined, allowing for the best price and justification for OEM equipment builders.

Most small pump clutches cost less than $100 and can, in many cases, double the life of a mobile pump. So, a small investment in a clutch can save money and increase uptime in various applications. For smaller pumps and engines, the Ogura MA Series clutches are available in torques ranging from 58 to 150 lb. ft. For pumps requiring higher horsepower, the MMC Series are rated from 200 to 1500 lb. ft. A variety of bore sizes and pulley options are available from stock.

Benefits you will see when using an Ogura electromagnetic clutch:

• Reduced engine load on cold weather starts
• Increased operational life of pumps and other driven equipment
• Fuel and energy savings
• Safety and convenience (remote starting)
