Vacuum pumps are some of the most commonly used devices on all sizes of vessels on the United States waters today, and there are many different types that boaters can use. Which type a boater decides on ultimately depends on several different factors. To avoid unnecessary costs, damages or hassles, you will want to make sure that you choose the right types of vacuum pumps for your budget and your boat. In addition to these however, there are also a couple of other types of pump designs that are also very popular.
Contrary to the vacuum pumps, some marine sanitation systems follow a diaphragm operation method. They rely on traditional pumping techniques to do the work and they work in a way that resembles a plunger. This plunger will fill up when the diaphragm lifts up, and the bowl is cleared whenever it falls. This action is what creates the suction action that causes the system valves to open and shut. If you are interested in this type of product, try to get a model that has an oversized inlet and outlet system so they can allow larger solids to pass through. Also of course you will want to purchase a system with a reputation for being durable and reliable.
Also in addition to vacuum pumps are the peristaltic versions.
A rotating positive displacement pump is used that is self priming. Two rollers within the device crush the contents into smaller size pieces that are confined within the housing of the device. The relaxation and compression alternates in the housing, which is what creates the suction and discharge pressure. These are popular because no contact whatsoever needs to be made with the contents that are pumped only the inner walls of the hoses should have any contact with the waste.
Finally we come to the vacuum pumps. Premium models have two tank designs that provide constant suction without the user experiencing any disruption of service. When one tank has filled up, the other tank moves its contents into the holding tank. The primary tank pulls vacuum and fills up until it is at its full capacity, when a sensor then tells the motor to reverse it. The first tank will begin to empty while the second tank will be the one to fill up. Many different types of systems are currently installed and used around the world, and some of them are available with all kinds of options including leak detectors, heavy duty hoses, corrosion resistant hardware and stainless steel frames, so be sure to research all of the vacuum pump options that are available to you.
