4.3. Filter press pump – TF…
The Tapflo filter press pump is a ready, compact product
that can be installed directly on the filter press. The pump is
equipped with a booster which amplifies the pressure in a
2:1 ratio. As a result we can achieve up to 16 bar on the
discharge of the pump (depending on pump size). As a
standard the booster is equipped with a pressure regulator
and two manometers. In comparison to a standard pump
the TF version is equipped with special pin screws and a
special air valve with PET piston (6-xxx-61-318).
In stainless steel pump series we also recommend to use
aluminium centre body (-6A option) instead of standard PP
for better durability.
Available for pump sizes:
• TF70, TF120, TF220 and TF420

is detected the pump is automatically stopped and an
alarm can be generated.
