Pumps designed to meet exacting standards

Flotronic’s 7in ‘H’ Style pump is a more compact model than the 10in, offering a pump solution when dealing with low flow rate applications. As with the 10in, the 7in pump sits on a stand so that the pump can be easily rotated. Gravity separates the ball valves from their seats in this inverted position allowing cleaning fluids to easily drain away. As with the 10in pump, 3-A standards regarding internal radii surface finishes and plastic parts provenance have also been met.

The 12in ‘H’ Series pump has a different solution to 3-A’s drainability requirements. At 75kg, it has check ball valve seats engineered to allow drainage without inversion. This avoids the need to rotate a relatively large machine and lets the pump remain in its normal operating position.

3-A SSI require that all materials are acceptable for product contact. Their standards also ensure that performance criteria critical to accepted methods of cleaning are met. The ‘H’ Style pumps are therefore designed so they can be thoroughly cleaned in place (CIP) with easy and effective media draining. The pumps also benefit from easy-maintenance, ONE-NUT design which allows pump maintenance in a matter of minutes.  

Jane Waite, managing director at Flotronic Pumps, says offering the range of low and high flow rate pumps broadens the appeal in the hygienic product transfer market: “Customers seeking low flow rate hygienic product transfer solutions and associated economies such as less air use will find the 7in ‘H’ Style pump particularly attractive,” she says, “while customers seeking flow rates as high as 500L/min will find the 12in pump ideal.”

The Flotronic ‘H’ Series pumps feature the option of reinforced diaphragms and reinforcing plates ensure the pumps can withstand CIP/SIP pressures up to 6 bar in the production line. This means the pumps can be Cleaned in Place using fully automated CIP units incorporating external CIP pumps, without the need to bypass the pump. 

All three Flotronic ‘H’ Style pumps are available with the option of BS, DIN or ISO hygienic connections. In addition, they all have an integral diaphragm rupture detection system. This shuts down the pump should a diaphragm fail, so product is not compromised.
