The SPL is a horizontal, single stage, end suction pump flanged to a bearing pedestal. The volute casing has integral support feet and is fitted with a replaceable wear ring. Wearing parts can be removed from the drive end without disturbing the volute casing and pipe work. An open impeller is fitted as standard but a closed impeller for pumping liquids containing abrasive solids can be fitted if required.
Series SPL volute-casing pumps can be used where the requirement is for pumping clean, turbid or slightly contaminated liquids. Occasional solid contaminations can be handled without affecting the pump due to the large internal cross sections. The SPL pumps are suitable for the following applications pumping raw water in waterworks as rainwater pumps, in sewage works for irrigation and drainage, as seawater pumps in desalination plants, as coolant pumps in power stations and steelworks for pumping low-concentration cellulose suspensions.
