Catalog excerpts

The Grifter is designed to meet domestic user requirements for handling raw sewage. Using a progressing cavity pump and tri-hammer macerator, this product is available as a unit only or as a packaged pump system. The use of a single motor drive directly coupled to the pump and macerator gives lowest possible design/construction and running costs. The Packaged System features duty and standby pumps, complete with all necessary pipework and factory assembled in a GRP kiosk. Integrally assembled below the pump kiosk is a glass fiber reinforced collection sump. Features • Positive displacement pump • Small bore pipe for rising main • Above sewage, ‘dry’ location of pumps • Tri-hammer macerator • Pre-assembled package with insulated G.R.P. enclosure, containing all pumps, macerator and control equipment • Total design, installation, commissioning and maintenance packages available Benefits • Slow speeds, low wear rates and optimum running time. Grifters consume less than 50% of the energy of conventional centrifugal sewage pumps. • Flow is finely macerated. • Lower installation costs, reduced risk of septicity and smells, greater freedom in routing layouts (will easily follow ground contours). Lower retention times allow a significantly better feed system to small treatment plants. • Routine maintenance can be carried out easily in a clean environment, in-situ. No sump entry risks or hauling pumps up out of the sump - no continual chain certification. • 3 hammer design gives very efficient product disintegration. • Rapid installation, low noise level, fully weatherproof. Can be installed in very remote isolated areas at much lower costs than a conventional pump house construction. • Only one order to one company - single sourcing. industrial@nov.com nov.com/industrial
