Multistage pumps

The pumps are flanged suitable for fitting directly onto the tank with the pumped liquid. The pumps are designed for pumping of cooling liquids with viscosity of max 30mm/s and maximum temperature 80°C. The pumps are not suitable for pumping of flammable or combustible liquids or used in explosive environments. The value of acoustic pressure is max 72dB(A).
