ZNA SeriesSunbo ZNA filter press feed pump suits for
various occasions such as coal dressing, environmental protection,
aluminum plant, steel plant, smelting, etc. The special
hydraulic design insures the pump performance curve is steeper
than common slurry pump, from big flow & small pressure to
small flow & high head.In the early process of feeding, the
valve is not used to control the motor overload caused by excessive
flow. At the same time, the low pressure will not impact the filter
plate frame, which reduces the damage of the filter cloth on the
filter plate frame, and will not impact the filter plate to cause
vibration, avoid pump holding, no leakage.Advantages1.
Special sealing device, Sunbo use lip seal and
high-class carbon fiber packing, wear-resistant shaft sleeve
to insure zero leakage with long time running.2. The
double-impeller design, make a much longer life time of the
feed slurry pump. Two impellers share the inner high pressure
seperately, decdrease the impeller and casing wear out. 3.
High abrasion resistance material, all wear parts made of
Cr20, Cr17, increase the life time maximally.4. Wide range of
applications-on the basis of the original 1450r/min, Sunbo new
developed a low-speed 970r/min slurry feeding pump. The new feed
pump runs with low speed makes the pumping system more table
running than single impeller pump. It can work with different
kinds if filters.ZNB SeriesIn recent years, the ZNB pump
called "special feed pump for filter press". The pump
sucks slurry from the rear side, and the packing
seal with no leakage. More importantly, its flow and head
curve is very steep, which is very suitable for some special
working conditions.Advantages1.The filter press feed pump with
high efficiency, abrasion resistance, running stable.2.Early Stage:
Big flow, small pressure; Later stage: small flow, big
pressure.3.Shaft seal: expeller seal, mechanical seal, no
pressure self-looping mechanical seal, end user could choose
freely.4.The filter feeding doesn't need frequency to
adjust speed. It can used for high concentration
medium.Working Principle1. At the beginning of feeding stage,
the filter chamber is empty and needs to be
full quickly. The ZNB filter pump is large
flow to ensure that the filter can be filled quickly.2.Boost
filtration stage: ZNB pump can work with big flow with low
pressure. As the feed pressure gradually increases, the filter cake
in the filter press becomes thick, and the water output of the
filter press begins to change from large to small. The filter
capacity of the filter press has also changed from large to small,
and the feed rate has also decreased.3.Pressure maintaining stage:
when the filtration pressure of the filter press rises to the
maximum condition, the feed pressure needs to maintain constant
pressure, and the filtration capacity of the filter press is
further reduced until the filtration is completed. At this time,
the ZNB pump press becomes the minimum and starts to maintain
constant pressure feeding.Select applicationThe main technical
parameters listed in this catalog are the data of the filter press
feed pump at 1480rpm.If low pressure requested,we could cut
impeller or decrease the pump speed. The centrifugal feed pump
suntion head is small, the medium height need higher than the pump
center height. Suction pipe size need be same or bigger of the pump
suction. /* March 10, 2023
