NPS PRO Mini Twin Ground Water Sump Pump Station (Pedrollo Top2)

Product Description

The NPS PRO MINI Twin Pedrollo TOP2 Groundwater Sump Pump Station is a compact, professional-grade twin pump system designed for effective groundwater management in basements, cellars and below-ground waterproofing installations.

Manufactured by National Pump Systems, this economical twin pump station combines the performance of two Pedrollo TOP2 automatic submersible pumps with a space-saving chamber design, making it ideal for installations where space and excavation depth are limited.

Each Pedrollo TOP2 pump is capable of delivering flow rates of up to 220 litres per minute and a maximum pumping head of 8 metres, providing dependable groundwater removal for basement and cellar drainage systems.

The durable MDPE chamber measures just 590mm in diameter and 600mm in height, with an additional 150mm high riser. Its compact construction makes it particularly suitable for smaller basement waterproofing projects and restricted installation areas.

The chamber incorporates four inlet positions arranged at 90-degree intervals, providing flexibility when connecting groundwater drainage systems. Installers can select from three inlet seal sizes to accommodate different pipework requirements.

Supplied with a 450mm round inspection chamber frame and lid, the NPS PRO MINI is compatible with a range of alternative covers, including double-sealed plastic and recessed galvanised options.

With its compact footprint, twin automatic pumps and practical installation features, the NPS PRO MINI Twin Sump Pump Station provides an affordable and effective solution for professional basement waterproofing contractors and drainage installers.
