Description
Engineering Application & Overview
Grundfos Unilift, DP, DPK, SE, and SL Series cover the full spectrum of submersible sewage and wastewater pump applications, from portable residential sump drainage (Unilift) through to large municipal sewage lift stations (SL1/2). The SE series features the S-tube impeller geometry, engineered to pass solid particles up to 65 mm diameter without clogging — the definitive solution for raw sewage handling in Batam’s developing residential and industrial waste infrastructure. The SL series with N-impeller is optimised for fibrous and stringy waste, making it suitable for shipyard sanitary waste systems and grey water management aboard vessels under maintenance at Marco Polo and PaxOcean facilities. Built-in moisture detection and thermal protection minimize unattended pump failures.
