THE SUMPLESS PUMP

The Sumpless pump is a simple and efficient way to get water from there to here without worrying about gravity feeding, 12 to 1 drainage slopes or sumps in the floor. The process uses some very simple principles to move large amounts of water with little energy and, as a system, integrates many other functions in one unit. Drainage is not a problem because the drain pipes are always empty and the water cannot backup if the pipe is empty! Even uphill pipe runs are acceptable (but not desirable).

The sumpless pump is a system to bypass the traditional sump to avoid having to monitor ground water levels due to possible leakage of the sump system. The sumpless pump works on a very simple principle which is applied to many different processes. As a drain collection system, the appropriate drains are plumbed to the check valve on the in put of the eductor. Solution is pulled with the eductor induced vacuum into the system. The system is sized for twice the expected flow. In batch treatment systems for small shops, a hose is run from the eductor to the tank to be emptied. In larger shops, the tanks are hard plumbed and drained directly to the eductor.

Theory of Operation:
The system operates by using the venturi principal (like an automobile carburetor venturi) to cause a negative pressure (partial vacuum) on the suction port of an eductor (got that?). The eductor itself is constricted at the center where the suction port enters. The constriction causes the solution to flow faster in this area over suction port. The increased flow and the configuration of the port creates the partial vacuum much like an airplane wing creates lift.

In operation, a large reservoir of solution is recirculated through the eductor causing solution from the process area to be sucked into the suction port on the eductor. The solution is entrained in the recirculation line and enters the reservoir. The solution is monitored in the recirculation line and the addition of treatment chemicals is also made in the recirculation line. This insures fast and accurate sensing and mixing. When the reservoir is full, a diverter valve is opened and the solution is pumped to the next process.

The system is used for pH adjust, cyanide destruct and chrome reduction. The system is easily configured for any "on the fly" processing. The suction port is fitted with a check valve to prevent solution in the line from backing up the drain to the process area.

The system is available with many options including:Flows of 8 gpm, 15 gpm , and multiples of 15 gpm Single or dual pumps Various sizes of collection tanks, fiberglass or polypro, 100 gal. up Various chemical additions including, pH adjust, ORP, polymer, etc. Filtration (media, bag or cartridge)
