New Brochure! Auger Pumping Systems


Mepaco’s auger pumping systems provide an alternative material handling option to traditional methods of dumping, screw or belt conveying.

Pumping systems are available as single or dual auger units and provide low-profile surge capacity where space is limited.

The key to any Mepaco auger pumping system design is to provide a first-in, first-out product delivery to mitigate shear, temperature rise or other changes that would affect product integrity in any way.

Polymer Bearings: Mepaco’s Customers Showing Promising Results

With the sophisticated demands in food processing and production, safety and quality, every component within food equipment is critical.   Any machinery with moving parts has friction and ‘wear’ issues, and to accommodate most equipment uses a standard bearing.   But in applications where the standard bearings compromise food contact areas, Mepaco offers the polymer bearing.

Standard issue bearings are typically ball bearings, mounted in a painted cast iron housing.   While the painted coatings are a sealant and deliver anti-corrosive benefits, rust and paint chips can still exist and find its way into the product path. Secondly, maintenance, disassembly, and replacement of bearings is very time consuming in a busy production setting. And lastly, if used above an open product path, grease may cause product contamination. For these reasons, steel ball bearings are best used in equipment and areas where they will not come in contact with food.

In food processing environments, producers should consider polymer bearings to mitigate food safety risks.

The polymer bearing has a moderate up front investment – more than steel bearings – but the Total Cost of Ownership is lower, because of fewer maintenance, safety and sanitation issues.

Mepaco’s polymer bearing is a solid, self-lubricating polymer that is absent of ball bearings. This ensures fewer parts, lowering the chance for breakage or malfunction. In place of the ball bearings, the polymer bearing includes a self lubricating insert, which eliminates the need for grease. That insert can also be replaced without needing to replace the entire housing, reducing the Total Cost of Ownership.

In recent Mepaco systems, the polymer bearing is showing much promise in new applications within traditional food processing environments. While not steel or cast iron in build, the polymer is ‘holding up’, proving to display the durability and efficiency in design.

Polymer technology is changing the face of many industries, and the food industry is no different. The advanced polymer bearings available in Mepaco products represent the promise of innovative components. And with a lower Total Cost of Ownership along with improved quality and efficiency, the smooth polymer bearing should be a reliable transition for all producers.

Mepaco working toward a 100% ASME Certified Welding Team


Among the value that Mepaco’s equipment provides, is the fact that Mepaco’s veteran welders are ASME certified. ASME welding certification guarantees a safer, stronger product.

Welding is an art among the science of manufacturing. The welder has the responsibility to provide artful, structurally sound coupons – with the independence, autonomy and accuracy presented by every challenging joint, bend or break in the metal.

But like any art, there is an associated range of quality with its practitioners. In our plant, ASME welders are highly skilled professionals certified to weld in all physical positions of a weld joint. This is the highest level of certification available. Mepaco invests the time and resources to ensure that all welders achieve this versatile level of quality.   The process starts on day one when new welders are hired.

Mepaco is the food processing equipment business group at Apache Stainless Equipment Corporation. Welders come to Apache with a variety of experience levels. Some come in with significant welding experience ready for certification. Others come with a desire to weld and a willingness to work. In those cases, Apache will invest in training and practice to ensure that these professionals develop to the standards Apache’s production requires. Most of Mepaco’s welding team is ASME certified with the remaining team members working toward certification. It is Apache’s goal that all welders be ASME certified.

Such a commitment to a high quality welding program speaks to the investment Apache makes in its workforce and skilled trades development. Apache has over 70 welding professionals on staff and works diligently with strategic community and educational programs to develop skilled trades.

ASME level welding quality is important considering the structural vulnerability within food processing equipment. A poor quality weld or a weld that has cracked can lead to cleaning issues and will likely harbor bacteria.

Because of ASME welding certification, Mepaco products rarely have welding warranty claims. Apache and Mepaco also have significant experience manufacturing pressure vessels for challenging applications that are built to be strong under pressure.

Apache continues to maintain rounds of audits and inspections by insurance and safety professionals that speaks to the consistency of the welders – and the effectiveness of the quality control department. Apache supports the ASME welding program within all our product groups: ASME large tanks, Portable Small Vessels and Mepaco, Apache’s food processing equipment line. Mepaco’s process customers are the biggest winners who will benefit from the best in build quality, efficiency and design.
