Frequently a customer will state that they have short pump lives and immediately the blame is placed on the pump. However, often it is not a pump problem at all, but rather a system or operational problem.
Generally, when someone mentions this it is not uncommon to associate the problem with the hydraulic conditions. In fact, oftentimes the issue is not on the liquid side of the pump at all, but instead it is a problem with the air supply. There are two types of common air supply problems; contaminated or dirty air and air starvation. Just as we need clean air to live, so does a pump. If the pump is clogged with dirt and debris it will be starved for air and not perform properly. The best way to keep your pump clean from dirty air is to install a filter regulator (Figure 1). A filter regulator is easy to install and provides the precise pressure control necessary to optimize pump performance and efficiency, at the same time preventing airline contaminates from reaching your pump.
Yamada offers a wide selection of filter regulators specifically selected for optimal performance with your pump (see chart).

The second main air side problem, air starvation, can be caused by several factors; a dirty air filter, a partially closed valve, an undersized airline/fitting or an undersized compressor. The best way to check if you are experiencing air starvation is to observe the air pressure gauge mounted near the pump. If there is not any swing in the gauge needle when the pump strokes, then you have a very good air supply. A swing of 10% is acceptable. If you get a wide swing, such as 70 PSI to 40 PSI, then the air supply may not be adequate, and the pump is starving for air.

If you are not receiving the proper air supply from your filter regulator, start by cleaning the air filter and check that the valve is clear of debris. Additionally, make sure you have installed the proper size airline, connections and air compressor. If, after taking the necessary steps, you continue to have performance issues, contact your Yamada distributor for further assistance.

Meat processing facilities, such as the poultry industry, produce wastewater with heavy loads of fats, oils, grease and solids. Before sending that water down the sewer drain, pre-treatment is required to remove as much of these solids and oils as possible. Removing these contaminants is simple with the proper designed DAF system. Yamada Pumps have been able to fill a “niche” in these systems, enabling better handling of the waste.
WHAT IS A DAF SYSTEM? Dissolved Air Flotation Systems (DAF) is a water treatment process that clarifies wastewater through the removal of suspended matter, such as, oil, greases or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin. The released air forms tiny bubbles which adhere to the suspended matter, casing the suspended matter to float to the surface of the water, where it may then be removed by a skimming device. PUMPS FOR HANDLING DAF SLUDGE. A multitude of positive displacement pumps have been used to transfer the DAF sludge; however, recently AODD (Air-Operated Double Diaphragm) pumps have become an option. Their ability to handle the viscous sludge and the ability to run dry without damage enables the pump to continue to run as the hopper empties. Conventional ball valve design AODD pumps (with bottom suction, top discharge) constructed in Aluminum with TPO or Buna N elastomers, were previously used. In poultry fresh (kill) plants, pieces of debris from the wash down would hang up the ball check valves, requiring regular tear down for cleaning. This would require the conventional AODD pump to be removed from service and completely tore down in order to clean out the ball check areas. STEP IN SOLIDPRO PUMP! Because the SolidPRO pump is designed to handle solids up to 2-inches and easy clean-out ports, it has quickly gained recognition as the preferred solids pump for DAF sludge.

EASY CLEAN-OUT PORTS! The SolidPRO clean-out cover plates enable access to the flapper check valves for easy flushing or cleaning.
Yamada has quickly become the pump of choice within the poultry and meat processing industry. Either handling the sludge off the dissolved air flotation unit, compressing sludge in the filter press, or transferring solid laden sludges to be a transport carrier, there’s a Yamada pump to fit into any waste water DAF system.
YAMADA WEBSITE As laws and regulations change around the country, you may start hearing about CBD and other products related to the hemp and cannabis (burgeoning) industry. Out here in the West, we’ve seen a ton of activity from the CBD Oil business. Whether building extraction machines for resale or for the use in their own facility, there are applications for diaphragm pumps. The caveat is, what the exact application in the process remains a mystery. Exact processes remain a closely guarded secret as there are several technologies for extraction. The three most common types of extraction are CO2, Ethanol and Hydrocarbon. CO2 is the most difficult, but appears to be the purest form of removal. CO2 allows for the extraction of oil without leaving residual oils and the need for more processing. It is CO2, in fact, where we see the lion’s share of the pumps being sold. As previously stated, the intricacies of the application are still somewhat shrouded in mystery, but we do know that Stainless Steel and EPDM are the materials of choice. Stainless for it’s resistance properties and EPDM for its ability to operate down to -40 degrees. Both standard SS and FDA pumps have been used as well as NDP and Tri Clamp fittings. NDP-25 Stainless Steel PumpLastly, the most common sizes that we have seen are the NDP-20 and NDP-25. For more information, visit www.yamadapump.com or call toll free (800) 990-7867. NDP-25 FDA Pump
Tis the season, for beer! The craft brewing industry is one of the hottest markets in our current economy. With over 160 facilities just in the city of Chicago alone, it’s an industry worth spending some time on. It’s a 26-Billion-dollar market and each one of these facilities could use our SS FDA pumps. They are used on the final products as well as cleaning applications in the breweries. For more information on what’s going on in your area, go visit www.brewersassociation.org plus check out our literature specifically designed for breweries here.
