4.1. Valve options
In T225, T425 and T825 pump sizes flap valves or heavy duty valve cups (not available in
T825) are available as an option instead of standard valves.
4.1.1. Flap valves
It is a great option when the product we intend to pump has high viscosity, contains big
solids or solids that can be damages by valve balls (e.g. fruits).
Mounted with clamps they provide easy maintenance and cleaning.
Flap valves made in AISI 316 are mounted in special flap valve cup with clamps between
housing and manifold. Pump with flap valves differ from standard pump by valve type,
manifolds (pos. 131, 132) and pump housing (pos.11).
IMPORTANT!
Flap valves are not appropriate for pumping water-like products. If a liquid has low viscosity,
the valve will open and close very fast with no shock absorption that is provided by viscous
products. Also dry running of the pump for longer periods will cause rapid valve wear and
eventually pump stopping.
