Beverages: Flavours, Colouring, Fruit Juice
Bakery: Dough, Ingredients
Brewery: Beer, Flavours, Colouring, Wort
Hygiene: Soap, Toothpaste, Shampoo
Cosmetics: Cream, Alcohol, Perfume
Variations:
Flap Valves –
Available on 3 pump sizes: T225, T425 & T825 Provide solids passage from 50 – 100 mm, model dependent. Provide Dry Suction Lifts up to 4.5 m Flap valves are a great option when the product to be pumped has a high viscosity and contains big solids or solids that can be damaged by standard valve balls (e.g. fruits).
Mounted with clamps they provide easy maintenance and cleaning. Made in AISI 316, they are mounted in a special flap valve cup with clamps between housing and manifold. Pumps with flap valves differ from the standard pump by valve type, manifolds and pump housing.
NOTE: 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. Modify your existing pump to be fitted with flap valves with the following additional parts:
Ball Cup Valves –
This option is a perfect solution when there is a risk of damage to the valve seats from the product. If such a situation is to occur there is no need to replace the whole manifolds or housings, just the valve cup what drastically reduces the spare parts cost. Just like the flap valve it is made of AISI 316 stainless steel and is mounted between the housing and manifold with clamps. In the same way, the manifolds, pump housing and pump stand have to be changed in comparison to a standard sanitary pump. The following additional parts are required to optimise your pump to be fitted with ball cup valves:
Heating Jacket –
A heating jacket is a great option when the pumped product tends to solidify at lower temperatures, e.g. chocolate or paraffin. When the pump has finished its duty and is left for some time without operation, the product can solidify inside. This is where the heating jacket comes in; before the next pump starts up, heat water or steam into the heating system for a defined period of time to melt the product inside the pump. Only then can the pump be started again with no risk of damage.
NOTE: When using steam as the heating agent, the flow must be from top to bottom (due to steam condensation). In the case of hot water or other liquid, it is the other way around. Do NOT exceed 2 Bar pressure in the jacket.
Magnetic Ball Lifters –
Magnetic ball lifters are implemented in the Sanitary and Aseptic
EHEDG series of AODD pumps to enable pump emptying without removing it from the installation when no other draining option is available. Rotating the pump is also no longer needed. The balls are lifted by simply attaching the magnets to the pumps manifold. Valve balls are available in AISI 420 magnetic stainless steel or PTFE with steel cores.
The Tapflo Sanitary Air-Operated Double Diaphragm Pumps have a wide range of capacities to suit almost any application, from metering and dosing to general transfer. The max capacity range varies from 30 – 825 l/min with discharge pressures up to 8 bar as standard & standard solids passage up to 15 mm or 100 mm with Flap Valves.
Connections:
The Sanitary Air Operated Double Diaphragm Pumps are supplied as standard with ISO Tri-Clamp connections. However, they may also be equipped with almost any type of connection used in the hygienic field – DIN clamps, SMS milk, RJT, DIN aseptic to mention a few.
