| Usage: Oil | Certification: ISO9001 |
The pump consists of two sets of pumps, which have different pump bores
in the serial form. The valve of oil input and output must be mounted to
the plunger. The plunger moves with the help of the feed-back force when
the pump is operating, so the pump is very suitable for sucking heavy crude
oil. This kind of pump can normally operate in viscous oil wells which the
viscosity of oil is over 40,000Pa.s. Besides, the pump has no standing valve,
so in the down hole, the drain is no use. Without moving the barrel and tube,
the subsurface testing and vapor injecting into viscous layer for thermal recovery
are able to be performed.

1) Plunger length: 600 - 1,200mm
2) Tubing size: 60.3 - 88.9mm
3) Length of stroke: 1,500 - 5,100mm
4) Suck rod: 22 - 30mm
