In addition, water pumps commonly come with Electrically Commutated Motors that contain magnets that attract any iron, or black iron oxide and magnetite, circulating in the water pipes. Over time though, iron accumulates on the pumps which in turn, causes failure. Obviously, this can be costly to the customer to clean, fix, or replace the pump motor. The 4900 Series with our new magnet option, totally eliminates that problem.

A UNIQUE DESIGN

Through the use of Taco’s patented Pall Ring design and technology, the 4900 Series uses coalescence to collect and merge micro-bubbles and allow them to vent through the integral vent mechanism at the top of the vessel. An optional switchable on/ off magnet clears the system of micro-bubbles as small as 18 x 10 -6 meters, magnetite, sand, dirt and rust. You can’t get a cleaner system than when using the Magnetic 4900-series separator!

Adding the new on/off magnet to the already great 4900-series separator, has taken it to the next level, differentiating their separator from all the others.

The magnet collects all of those afore mentioned metal shavings that are continually circulating through the system. To flush them from the system, just turn the magnet off and open the flush valve. The metal and dirt flushes out easily. Turn it back on and the system is up and running again quickly. No need to take out the magnet for cleaning and clearing debris, which results in easy maintenance for a reduction in labor and down-time.

This is a unique feature to Taco and is a game changer for you.

Sometimes really cool projects fall your way. This giant stainless-steel air separator was one of them. A customer called asking if Taco made “custom” tanks, air separators, etc. Of course, Taco is capable of building virtually anything made of metal / steel that can be fabricated, and everything is ASTM certified. The customer needed a VERY large, custom air separator for a process application and the system required that the air separator be constructed entirely of stainless-steel.

Removing air and dirt from any hydronic system is critical to maximizing system efficiency and most importantly, for prolonging the life of the pumps and the rest of the equipment in the system. The project was a tall order, literally, but Taco was up to the task!

Custom Design

The design was based on Taco’s top-of-the-line 4900 series air and dirt separator with some very unusual dimensions; 132” (11 feet) tall and 66” (5.5 feet) in diameter. Flow requirements necessitated the tank to be 30” in diameter!

Once we had the requirements from the customer, we asked Taco engineering to provide design and full submittals, including drawings, pressure drop calculation and minimum / maximum conditions of the unit. After the submittals comments and design were finalized, the unit was released for fabrication using ½” wall, 304 stainless-steel. All work was performed in-house by Taco craftsman, using Taco equipment, including rolling the ½” wall steel on their own rolling equipment. Taco’s fabrication shop, certified welders and capabilities are second to none in the industry!

A Small COVID-19 Setback

The project began, just as the COVID-19 virus hit, requiring Taco to shut down briefly, then adjust to local (Massachusetts) state ordered production rules. This reduced the total weekly operating hours, limiting them to four-day shifts, and requiring sanitization of the entire facility at the end of each week to ensure the safety of their employees.

Despite this, Taco’s Fall River Massachusetts facility (the pumps and drives are made in Rhode Island) completed the fabrication, pressure tested the unit and shot-blasted it prior to shipping it. According to Anthony DeMoura, Taco’s Vice President of the Fabricated Products Division & PIFA Foundry Operations, this was the largest stainless-steel vessel they have ever made.

Specialized Shipping

A specialized cartage company had to be used because the air separator weighed four tons! As you can see from the photos, the design, transportation, and install was a tremendous success! Everyone involved in the project pulled together in order to make this custom air separator and the unit was featured in this month’s Taco newsletter.
