Mud Pump Liner, Ceramic Liner, Bi-Lateral Liner, Premium Liner
Tiptop is specialized in manufacturing and supplying wide range of
replacement parts and liners, fluid end modules for brand name mud
pumps, including Emsco, National, Oilwell, Ideco, Gardner Denver,
and also China Origin like CS, BOMCO, RG, etc. We have the
professional technical engineers who have many years’ experience in
designing and producing of this line.
Bi-lateral Liner, Premium Liner
Our premium liners combine the strength of a forged steel outer and
corrosion resistance of a high chromium iron inner sleeve. These
liners feature a centrifugally cast high chrome iron sleeve which
is machined and heat treated strictly to hardness of HRC≥61~64.
Each liner is machined to close the tolerances to assure easy
installation and long liner life with the inside diameter of these
premium liners honed to a mirror-like finish or smooth even wear
during the life of the liner. Tiptop premium liners are made for
superior performance under tough corrosive and abrasive conditions.
The service life of our liners is proved to generally reach a level
of more than 800 hours in high pressure, which has earned us
reputation from worldwide customers.
* Hy-chrome liners made with a high chrome sleeve in a forged steel
hull
* The bore hardness is 60 to 65 Rockwell C scales
* Service life more than 800 hours under the normal condition
Ceramic Liners
Our ceramic liners combine the strength of a forged steel outer
with the abrasion and corrosion resistance of a ceramic inner
sleeve.
* Suitable for deep oil reservoir, hard stratum and severe
earthiness, offsore oil and natural gas exploitation
* Service life more than 4000 hours under the normal condition
* Wear-resistance, Erosion-resistance, High-pressure-resistance,
High- temperature-resistance
* High strength and high hardness
* Reduce piston wear and water consumption for lubrication
