LFM 'MSP' type Annular Blowout preventer / Diverter has been developed to fit for low pressure drilling service with simple and reliable structure design. Piston and Packing Units are the only two moving parts which can reduce the wearing area thus can shorten the maintenance and downtime. Two sizes of 'MSP' type Annular BOPs are available in LFM - 21 1/4" - 2000psi Annular BOP and 29 1/2" - 500psi Diverters.
The 'GK' type Annular BOP is a universal Annular Blowout preventer and it is designed especially for land drilling application. Thie type BOP is safer and more efficient, requiring less maintenance and less downtime.
