TNSM Monoblock Centrifugal Pumps
Compact monoblock end-suction centrifugal pumps for clean or slightly dirty, non-abrasive, low-viscosity liquids without solids or fibers.
Desan Engineering TNSM series pumps are designed for clean or very slightly dirty, non-abrasive, low-viscosity liquids that do not contain solid particles or fibers.
They are single-stage, end-suction closed impeller monoblock centrifugal pumps with volute casing — motor and pump form one compact drive unit.
Highlights
- Pump shaft supported by the motor bearings
- Shaft sealing by mechanical seal (standard)
- Casing dimensions comply with TS EN 733 / DIN 24255
- Suction and discharge flanges: TS EN 1092-2 / PN 16
- Electric motors compliant with VDI standards and IEC frame sizes
Materials and seal may change with liquid density, temperature and pressure. Casing and impeller can be produced in bronze or stainless steel when required.
