Description
Zibo KNC Petroleum Equipment covering *8,**0 square
  meters with building area of *3,**0 square meters,
specializes in producing
  various kinds of plunger pumps, mud pumps and other
petroleum machinery
  equipment as well as related spare parts.
  The pumps we produce enjoy longer service life,
since the
   following problems are settled.
1. Material: Smelting technics and material composition are
strictly required
  to be in accordance with the international
standard. Advanced
  detection devices (such as metal spectrograph) are
equipped to verify
  and guarantee the mechanical strength of metal
material meeting the
  use requirements.
2. Pump casing is processed by high-precision CNC machining
equipment to
  ensure the perpendicularity within 0.*2mm between
the crankshaft and
  three holes of the crossheads and parallelism of
the three holes within
  0.*2mm. Thus, the reasonable operation of each part
is fundamentally
  ensured and the service life of the pump is
extended.
3. The company has its own rubber,polyurethane research
institutions and
  production plants.It equips testing instruments for
material tensile strength,Â
  wear, cracking, elastic deformation,
low-temperature brittleness , and
  special experimental plate-form for checking the
service life of rubber and
  urethane seals. Its wide range of packing, valve
rubber and piston rubber all
  reach the level of the similar products abroad and
extend the service life of
  the pump.
4. US supersonic flame spray technology is introduced to spray
plunger and
  other wearing parts with tungsten alloy. The
hardness can reach HRC*5 or
  more, which greatly improves the wear resistance
and service life of parts.
