All Metal Bare Shaft Slurry Pump 50ZJ-A50 with a Lead Time of 10
Days
Introduction:
ZJ slurry pumps are high-pressure slurry pumps with big flow and
high heads. They can be used for many applications where the
War-man type HH series pumps can't suit.
ZJ slurry pumps are designed and developed by China's local
engineers. They are designed for abrasive sludge with a high head.
The ZJ slurry pumps are widely found in coal washing plants, power
plants, and even mining companies.
Equally Suitable for handling abrasive slurries or combinations of
abrasives and corrosive solutions, SME ZJ pumps will solve pumping
problems outside the scope of metal and other types of pumps. The
many duties for which ZJ pumps have been used are:
Sand plants; Coal preparation plants; Chemical works; Metalliferous
mining; Paper mills; Steelworks; Power stations.
The SME ZJ pump range has proven performance and wears advantages
that will re-write the Total Ownership Cost equation for many
end-users.
Oil being lubrication with labyrinth style bearing seals.
Internal liners can be fully worn before replacement as the ductile
iron split outer casing provides structural strength to contain all
design operating pressures regardless of the worn condition of the
liner. Multiple seals are available: gland seal, mechanical seal or
large diameter expeller seal.
Like ZGB pumps, ZJ pumps are also made of hard metal material only.
The ZJ pumps can pump very high pressure. If you are looking for
applications where you need to pump the water slurries to over 80
meters, then ZJ pumps are one of the better solutions.
