Introducing the SN3

A Rugged Well Water Pump






Call us today!





The SN3 is a pump that will perform years of service if treated with reasonable care. This pump is named SN3 for Sandy Neck Beach in Barnstable, MA. The logo shows a map of Cape Cod; Sandy Neck in particular. "Out on “The Neck,” there are no town electric or water services. Back “in the day,” in order to get well water you either pumped it by hand, brought in a gas operated pump, or an electric pump ran off of a gas powered generator. With the advent of solar and wind power we now have limited 12 VDC (VOLTS DIRECT CURRENT) and 110 VAC (VOLTS ALTERNATING CURRENT). Running devices right from 12 VDC is by far the most efficient method. Most 12 volt pumps won’t lift more than 10 feet, and if there is the slightest leak in the suction line…there goes your suction (prime)! Most 110 VAC pumps are of the centrifugal type and they are just too inefficient when you’re trying to live within your means when you’re generating your own power. They will lift about 25 feet, but they are energy hogs! I found a similar antique (1950’s) pump that was a small but heavy, double acting, positive displacement pump powered by 12 volt motor. The SN3 is based on this type of pump. I started experimenting with pumps, and what you have here in SN3 is the Sandy Neck 3rd generation pump. Small, portable, and robust! The pumping parts of this device are made solely of corrosion resistant materials, stainless steel, PVC plastic, neoprene and silicone rubbers, and Teflon packing. Because of this you can pump both fresh and salt water! Avoid oily waters, such as from boat bilges, oils attack PVC.
