Security: Explosion-protection, water-safety, security valve, alarming sensor.

B. Utilizing area
one. CZPT CZPT: Transfer pump for a variety of lubricating oil, crude oil, residual oil, large oil, biHangZhou, diesel oil, gasoline and so on.
two. Shipbuilding CZPT: Transfer pump, cargo oil pump, booster pump, striping pump and engine lubricating pump for different gas oil, lubricating oil, waste oil, bilge sludge and sea h2o and so forth.
3 CZPT CZPT: Transfer pump for various acid, alkali and salt solution, resin, glycerin, olefin, polymers and various cosmetics emulsion.
four. Paint CZPT: Transfer Pump for numerous printing ink, paint, oil paint, dope etc.
5. Foods CZPT: Transfer pump for various large-viscosity medium like alcohol, beverage, honey, sugar juice, tooth paste, milk, soy sauce, animal oil, vegetable and chocolate and so on.
6. Preserving & Transferring sector: Loading and unloading oil products for oil station, ship and tanker.

C.     Features
one, The inlet-outlet civility adopts specific design and style to make sure that enough medium is remained in the pump. Even when the medium in the suction pipe is all discharged, the pump still has very good self-suction efficiency.

2, The pump entire body adopts special-structure round valve, which will open up when the outlet strain is larger than the working stress. Then, some medium will back again to the inlet of pump or saving can via this circular valve. Meanwhile, the pump can starts underneath entire pressure scenario therefore significantly lessen the torque.

3, Use synchronizer gear to transfer toque from initiative screw to idler screw, which guarantees no steel get in touch with and electrical power transmission among transferring elements. So the transferring elements have higher reliability for any medium and the pump can totally free from hurt of dry rotation in a quick time.

four, When the pump is doing work, the meshing screws type a sealed civility in the pump physique, following the rotary motion of the screws, the liquid in the sealed civility does axial movement with the sealed civility and transferred to the outlet of pump steadily and constantly. Because the potential of the sealed civility in no way modifications in the doing work pump, there will be no pulsation when the pump deliveries liquid.

5, The entire body of twin screw pump has numerous distinct heating composition strategies for option, to adapt to diverse medium under various temperature.

D.     Other Details
Our pumps can be created in accordance with the specific demands of consumers: Horizontal, Vertical, Trolley structure Explosion-proof degree, Diploma of CZPT, insulation degree(for hazardous area working), specific stainless metal for special need(foods business, corrosive liquids, etc), heating chamber, basic safety valve, alarming sensor, and many others
Our pumps(primarily twin-screw pumps)and programs are the perfect remedy for tanker terminals, oil production and processing.

Multistage Dry Vacuum Pump Gas Way


CZPT dry vacuum pump Gasoline Way


  • Airflow route radial, Corrosive approach fuel does not attack the bearing and gear axially immediate
  • Airflow path axial, Corrosive procedure attack the bearing and equipment axially in gear cap violent
  • Method gas is compressed uniformly in each and every stage of rotors. Uniform compression heat, so decrease exhaust fuel temperature
  • The method gas is compressed centrally at the finish of screw, so higher exhaust gasoline temperature and screw
  • Approach gas could contact with far more cooling jacket floor, high heat dissipation performance
  • Method gasoline could speak to with handful of cooling jacket surface, reduced heat dissipation
  • Roots rotor is much more resistant to particles and adherents, number of impacts on its functionality after its surface use and corrosion
  • CZPT rotor is unsuitable for particles and adherents, big impacts on its performance soon after its surface dress in and corrosion
