expansion vessel for potable water, pumps and booster sets
capacity: from 24 - 3000 litres
ULTRA-PRO pressure tanks are the best choice for irrigation pumps, centrifugal pumps, submersible pumps and
for booster sets. The capacity of a bladder tank is larger than the capacity of common storage tanks: the same
performance can be obtained with a smaller volume, allowing minimum pump starts therefore saving energy.
The range of different sizes, availability of vertical and horizontal models, together the choice between galvanized
or stainless steel flanges ensure that the ULTRA-PRO pressure tanks meet the requirements of the end user. Pressure
tanks from Zilmet undergo 100% factory testing procedures and are certified according to PED 97/23/EC.
The bladder, which is suitable for alimentary purposes, is fixed at both ends avoiding any possible contact against
the inner tank surface.
ULTRA-PRO pressure tanks offer unlimited service as the bladder is easily replaceable.
MIG welded carbon steel body without internal rough spots or sharp edges. Replaceable bladder suitable for use
with potable water. Painted externally with long lasting epoxy powder. Mild steel or stainless steel flanges for use
with aggressive water.
When the pump starts, water enters the membrane tank as system pressure passes the pressure precharge using
the whole capacity of the tank. Only usable water is stored. When the pressure in the chamber reaches the
maximum system pressure, the pump stops working. The tank is filled to its maximum capacity. When water will be
needed again, pressure in the air side will push water into the system. Since Zilmet ULTRA-PRO tank does not water
log and delivers all possible water, minimum pump starts are assured with saving on energy consumption and
increasing the pump life.
