Standard water pumps SN by Tuma

For pure liquids, slightly contaminated liquids

These horizontal, single-stage, radially split volute casing standard pumps SN from TUMA are suitable for clean or slightly dirty liquids with low viscosity. The standard pumps are available with a closed impeller.

In a variety of designs, all SN models comply with the DIN 24255/EN 733 standards and the suction and pressure flanges comply with the ISO standard. All impellers of these volute casing pumps are ISO 1940 Class 6.3. dynamically balanced.

An absolute advantage of the SN standard water pumps is the back-pull-out design, which allows the entire bearing including the impeller and shaft to be dismantled, with the housing remaining in the piping system.

In the SN standard water pump, the bearings are “lubricated for life” rolling bearings. The axial thrust is balanced by a wear ring/balance hole system.

Areas of application for these standard pumps are: irrigation and water treatment systems, cooling and heating systems, air conditioning systems, beverage and food processing, chemical and petrochemical industries, paper and cellulose industries, power plants.
