Our Sanitary series of Diaphragm Pumps has been specifically designed to meet the requirements of the food, beverage, pharmaceutical and cosmetic industries, offering FDA, EHEDG, or USP VI certifications.

All Tapflo Diaphragm Pumps have been designed with simplicity and innovation in mind; they have a compact, robust and reliable design that makes them popular across the globe. Significant in hygienic industries, our pump range is quick and easy to maintain, keeping servicing costs and process downtime to a minimum. We have a range of Pneumatic Diaphragm Pump accessories available that provide control and monitoring that aid with preventative and routine maintenance. This not only ensures your pump is operating efficiently but ensures our customers can optimise their systems to the best of their ability for accurate, precise and efficient performance.

The major features of our Sanitary Diaphragm Pumps include:

  • Lubrication-free air distribution system
  • Maintenance-free ball check valve system
  • Total visual inspection of the wetted parts
  • There are no hidden areas where bacteria can grow due to the high-quality finish of the pump housing, extra-fine surface finish to Ra 0.8 as standard and 0.5 upon request.
  • It supports CIP and SIP & can turn 360° to drain the pump
  • Manifold clamps and the housing screws are simply removed for complete disassembly and cleaning.
  • Clean face, no-nut diaphragms to reduce the risk of leakage and simplify cleaning. The smooth surface of the diaphragm face also eliminates the likelihood of bacteria developing on them.

The Tapflo Sanitary Air Operated Diaphragm Pumps are ideally suited for a range of hygienic applications and industries, such as:

Dairy Products: Milk, Cream, Yogurt, Cream Cheese, Melted Cheese

Grocery: Ketchup, Mayonnaise, Tomato Products, Mustard

Beverages: Flavours, Colouring, Fruit Juice

Bakery: Dough, Ingredients

Brewery: Beer, Flavours, Colouring, Wort

Hygiene: Soap, Toothpaste, Shampoo

Cosmetics: Cream, Alcohol, Perfume

Variations:

Flap Valves –

Sanitary Diaphragm Pump Flap Valve

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:

  • T225 = Flap Valve Compete x 4 (P/N: 6-225-24H)
  • T425 = Flap Valve Compete x 4 (P/N: 6-425-24H)
  • T825 = Flap Valve Compete x 4 (P/N: 6-825-24H)

Ball Cup Valves –

Sanitary Diaphragm Pump 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:

  • 4 x Ball Valve Cups
  • 2 x Manifold for Ball Cup Valves
  • 2 x Pump Housing – Ball Cup Valves
  • 8 x 3-Clamp Seal
  • 4 x 3-Clamps
  • 4 x Valve Ball Stops
  • 4 x O-Rings
  • 1 x Pump Stand

Heating Jacket –

Sanitary Diaphragm Pump with 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

Magnetic Ball Lifters on Tapflo's Sanitary Diaphragm Pump

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.

Sanitary Diaphragm Pump Technical Specifications

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.

Pump Emptying Procedure:

  1. Install the magnets onto the pump manifolds in the valve seat area
  2. Run the pump slowly
  3. After a few cycles, the pump will start to dry run
  4. Turn off the pump
  5. Take off the magnets & manifold

Modify your existing pump to be suitable for use with Magnetic Ball Lifters with the following additional parts:

  • 4 x Valve Balls (PTFE Steel Core or AISI 420)
  • 4 x Magnetic Ball Lifter
  • 1 x Magnet Holder
