The GemmeCotti HTT 2000 is the smallest pump in the HTT magnetic drive turbine range, built for transferring corrosive chemicals safely at low flow rates. It delivers up to 1.7 m³/h with heads up to 10 metres through 1″ BSP connections. The sealless magnetic coupling removes the mechanical seal entirely, so there is no leak path and minimal maintenance.
This page includes the HTT 2000 in polypropylene for liquids up to 60°C and PVDF for demanding duties up to 90°C. Both versions use a PVDF impeller, a 99.7% alumina ceramic static shaft and PTFE-carbon bearings for excellent chemical resistance. The pump weighs just 2.8 kg in PP or 3.8 kg in PVDF, so it is easy to position within compact installations.
Choose a bareshaft pump head to couple with your own motor, or a complete unit fitted with a 0.37 kW, 50Hz motor in 230v single-phase or 400v three-phase. Like the rest of the HTT series, the 2000 handles up to 20% entrained gas and allows the ports to be reversed by changing motor rotation. It is rated PN 6 and suits clean liquids up to 45 cPs viscosity.

The HTT 2000 delivers a maximum flow of 1.7 m³/h and a maximum head of 10 metres. Performance figures are based on clean water at room temperature, so allow for viscosity and density when pumping other liquids. It runs at 2800 rpm on a 50Hz supply.
Yes, both material options are designed for corrosive chemicals including many acids and alkalis. Polypropylene covers a broad range of duties up to 60°C, while PVDF extends resistance and temperature capability to 90°C. Always confirm compatibility with your specific chemical and concentration before ordering.
Yes, the regenerative turbine design tolerates up to 20% entrained gas. This gives it strong resistance to cavitation compared with conventional centrifugal pumps. The liquid itself must still be clean and free from solids.
The wetted casing material changes, which affects chemical resistance and temperature limits. PP versions use EPDM O-rings and suit liquids to 60°C, while PVDF versions use FKM O-rings and handle up to 90°C. PVDF also resists a wider range of aggressive chemicals.
