Speck DS 5-12

The Speck Pumpen Speck DS 5-12 is a self-priming pump. It is normally installed in bilge, stripping, drainage, deck or general-service systems where liquid may lie below pump level. It is designed for establishing suction and moving liquid without a permanently flooded suction line. In operation, an internal priming/separation arrangement removes entrained air and restores liquid flow. The supplied entry states the pressure designation as 12 bar; this information is retained unchanged. Compared with neighbouring models, the relevant differences are flow, pressure, suction-lift capability, materials and internal pump design; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on priming performance, suction air leaks, seals, strainers, bearings and non-return valves. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.
