Marine Pumps

Dosing pump, metering pump (plunger dosing pump, hydraulic diaphragm dosing pump, mechanical diaphragm dosing pump)
The dosing pump is a special reciprocating displacement pump, of which the discharge can be infinitely regulated between 0 and 100% to feed corrosive and non-corrosive liquid at a certain amount for the purposes of different process flows. It includes plunger dosing pump, hydraulic diaphragm dosing pump and mechanical diaphragm dosing pump. The products comply with GB/ T7782-1996, CE dosing pump standard.
Dosing pumps are extensively used in such industries and sectors as petroleum, chemical, water treatment, environmental protection, food, light industry, paper-making, pharmacy, dyeing and finishing, metallurgy and mining. 

Marine pumps

Offering a range of marine pumps, centrifugal pumps, marine jet pump, diesel fire-pump, marine vertical centrifugal pumps, horizontal centrifugal pumps, submersible pumps, vortex pump, sea water pumps (CPT, CPJ, CWY, CL CLH, CLZ, CIS, CWF, CWL, CWZ, CYZ, DNW, CQX, CX, CXZ, CWX, W, WZ, CS, CB, ZYG), are widely used in the ship row hydrophobic, emergency fire, bilge ballast, cooling pumps, desalination of sea water, hot and cold water cycling, sanitation pumps, sewage pumps,  life-saving emergency.

Marine pumps are ideally suited for saltwater, as well as brackish water and waste water applications. These alloys offer superior resistance to corrosion/errosion in saltwater applications. 

Certificates achieved include ABS, BV, CCS, DNV, GL, KR, LR, NK etc. 


We are constantly seeking for new talented people. Attracting high potentials from every background or culture, offering them experiences and opportunities to develop their strong potential and engineering skills. Wisdom Int. Trade (S) considers as the best strategy to face its future challenges.
