How a Double Disc Pump Works

We have all seen the outside of a double disc pump but rarely do we see what makes the pump actually work. Just to review, a double disc pump is a positive displacement pump that uses a trunnion (elastomer), a disc and a connecting rod to force sewage from the suction side to the discharge side of the pump by creating a vacuum inside the pump body. The valve chambers with the black check valves you see in the photo help to manage higher than normal concentrations of grit and solids in municipal wastewater.

Pumps: How to Maintain a Continuous Flow and Minimize Pulsation

With pumping applications, one of the challenges you face especially when pumping thinner liquids, is to maintain continuous flow without “jerking the hose” or disruptions in pump productivity. One of the consulting engineering firms we have worked with in California illustrates this point well:

Drinking Water Transportation Systems

One of the questions we get from municipal emergency management agencies and larger corporations is if there is an economical method of providing clean drinking water via trailer or skid. Gilbert K from Clay County TN exemplifies some of the concerns about providing potable water in his community:

We have a rural community of about 20 residents where drinking water is not always accessible. A water truck service has been costing us a fortune to fill the residential drinking water tanks serving the homes. We are trying to reduce our budget by possibly investing in our own water trailer system but the unit has to be safe for storing and dispensing drinking water. We would be filling the water trailer either at the municipal water treatment plant 20 miles away or by a fire hydrant closer to the community. We also want to make sure that an F-150 truck can safely tow this trailer full. Please provide suggestions and a budgetary proposal. Thank you Gilbert – Clay County, TN USA.

Gilbert, you have a lot of options to provide your own municipal drinking water transportation system. We call it a water trailer or water wagon. We have supplied disaster relief agencies and emergency management government with the WT-500-DT for years – see the pictures in this post or click on the photo to see the website specs of the unit.
