Unibloc Pump displayed its QuickStrip positive displacement pump (1) for fluids, which features an all-stainless design with no rotor bolts or O-ring, helping eliminate the most common causes of foreign material entering the process stream and reducing damage during sanitation.Image #1 in the article text.Image #1 in the article text.

According to Unibloc Pump Sales Engineer Pelle Olsson, the pump has a sanitary swing arm that comes out from the side of the bearing housing and holds up the front cover. “This is both a safety and a sanitary design,” says Olsson. “It keeps the front cover off the floor and free from damage.”

A unique feature of the rotor design is that it has no rotor bolt. “It’s designed for manual clean or COP applications in the food, cosmetics, or pharmaceutical industries,” says Olsson. “The rotor comes out with your fingertips. It’s all stainless steel. There is no O-ring behind it, and there are no O-rings on the rotor bolt.”

With fewer components than other sanitary pumps, QuickStrip pumps can be assembled and reassembled with no tools, minimizing wear and tear during sanitation cycles.

Brand new at PACK EXPO Las Vegas was the FCM Colloid Mill (2) from Fristam Pumps. Designed for products such as sauces, dressings, mayonnaise, and a range of oil and fat emulsions, the new system saves time between batches because it’s never necessary to open the mill between products—either for product change or for cleaning.

The FCM system has a variable gap adjustment that lets the user easily change the gap for more or less shear, reducing fat particle size as necessary, explains Jim McCoy, sales manager for Fristam Pumps. It is not necessary to move the inlet or outlet ports or even pause operation. The system also enables hands-off clean in place (CIP), simply adjusting the gap to its maximum setting to CIP through the mill.Image #2 in the article text.Image #2 in the article text.

The FCM’s variable gap makes it possible to dial in the particle size needed for shelf-stable emulsions. It allows for consistent particle sizes with a tight distribution.
