One Pump fits all Needs at Saba

In total, Saba has upwards of 30 Wilden AODD pumps in operation, including several T8 (51 mm) models that have been operating faithfully for more than 20 years. “Over the years, we’ve had a lot of different brands of air-driven pumps in the factory and we were always looking for a pump that we could use everywhere and had the special features that we needed,” said Blom. “With other brands, it was hard to get Teflon membranes and we are able to do that with Wilden, and the price of the pumps is good considering the quality we get. With Holland Air Pumps, we also have a partner that can deliver all the spare parts we need, and if we need a new pump, in a few days we have a new pump because they have all of the parts in store.”

Rarely, if ever, are any spare parts needed because the pumps are virtually leak–free, which means that not only are costly cleanups avoided, but so are the ancillary manpower costs that go with them. “With other types of pumps we had to clean them every week, which took 1.5 to two man–hours. With the Wilden pumps we are cleaning them every three months or so, which is a huge savings in man–hours per week,” said Zaarbelink. “We also found that most of the competitive pumps after a certain time will have an internal leakage that means the raw material will get into the pump’s air engine. We find that with Wilden the diaphragms really stand up to aggressive materials for a really long time.”

AODD Pumps

The Perfect Partner

While air–operated double–diaphragm (AODD) pumps from Wilden make up the bulk of the pumps that Saba Dinxperlo uses in its adhesive–manufacturing systems, the company has found additional success with the products from another member of the Dover Corporation’s Pump Solutions Group (PSG): Almatec from Kamp–Lintfort, Germany, is a premium manufacturer of AODD pumps that have a solid–body design, are dry–run and self–priming capable, offer gentle product displacement, can handle solids and feature the patented Perswing P air control system.

Specifically, Saba utilizes several Chemicor Series pumps in its production processes, which have been supplied by Holland Air Pumps, an exclusive distributor of Wilden and Almatec in The Netherlands. Chemicor pumps offer a compact, solid design that feature product chambers with soft contours that result in smooth flow channels and no dead spaces in chemical–processing applications.

“We have incorporated some Almatec Chemicor Series pumps where appropriate into our operations and they are ideal because they produce less noise and are so easy to use,” said Tonny Zaarbelink, Technical Manager Foam Bonding for SABA. “Their solid construction also makes them perfect for use in handling the specific raw materials that are required in adhesive manufacturing.”

Efficiency for Adhesives

Saba has recognized the potential pitfalls in manufacturing adhesives and sealants, and has worked for 80 years to remain innovative and create products that satisfy the needs of many industries. Side–by–side with Saba for the past 20 years, Wilden’s stainless-steel AODD pumps have provided the reliability and operational excellence that manufacturing glue and adhesives demands. “Twenty years ago we switched to Wilden pumps and we have stayed with them ever since,” said Zaarbelink. “After 20 years we have found that they are very reliable. The ongoing maintenance costs are very low, so we are very happy with the Wilden pumps.”
