Description

Design Features :
Power End :
•The frame is of welded-steel pale construction , with characteristics of high strength , good rigidity and light weight due to internal stress eliminating treatment after being welded .
•Integral herringbone gear drive is adopted for smooth running , high efficiency and long operating life . The crank shaft is alloy steel castings .
•Double-deck sealing is adopted in intermediate pull rod with sound sealing effect .
•The power end adopts the lubricating method of forced lubrication combined with splash lubrication .

Fluid end :
•The hydraulic cylinder material is alloy steel forging . Straightway hydraulic cylinder has good suction performance .
•Suction valve and discharge valve on F series pump are interchangeable .
•Pump F-500 uses API 5# valve ; pump F-800 and F-1000 use API 6# valve ; pump F-1600 uses API 7# valve.
