RL3NB1300D mud pump is designed and manufactured to optimize structure to achieve the highest precision and deliver maximum performance and efficiency.

Feature:

u       Welded steel plate frame with high strength, good rigidity and light weight assure smooth operation at high power drive.

u       Enlarged the fluid cylinder, Added four studs which connect front-end bulkhead directly.

u       Front-end plate and side plate have been increased in thickness.

u       Lengthen connecting rod to minimize the friction.

u       Enlarged the skid to assure smooth operation under high pressure.

u       Combined lubricating system of forced lubrication ad splash lubrication, with oil pump to feed working parts.

u       Complete piston drenching and lubrication system.

3NB series Option:350hp,500hp,800hp,1000hp 1600hp,2200hp pump and customization is available.
