Alfa Laval SRU6/260

This listing concerns an Alfa Laval SRU6/260 industrial pump manufactured in 2019. The pump is engineered for heavy-duty industrial applications, featuring a specified displacement of 2.60 liters per revolution and a maximum nominal capacity of approximately 93.6 m³/h. It operates at a maximum rotational speed of 600 rpm and can handle pressure differentials up to 10 bar for the stainless steel LS/HS version or 20 bar for the Duplex LD/HD version. The pump’s connections are sized at DN100 (4 inches) and can pass solids up to 18 mm in diameter.

Media-contact parts are made of AISI 316L stainless steel (W. 1.4404) or optionally Duplex steel, with a standard surface finish of Ra ≤ 0.8 µm. The pump is fitted as standard with tri-lobe rotors, with an option for bi-lobe rotors for larger solids. Shaft sealing solutions include single mechanical seals (R90), double flushed mechanical seals, or packed gland seals. Available elastomers are EPDM (standard), with optional NBR or FPM choices.

The pump assembly includes an electric motor and gearbox supplied by NORD DRIVESYSTEMS. The motor is model SK 132SP/4 TF rated at 5.50 kW, and the gearbox is SK 33-132SP/4 TF with a torque of 276 Nm. The motor operates at 1465 rpm at 50 Hz and 1770 rpm at 60 Hz, delivering IE3 efficiencies of 90.9% and 91.7% respectively. Both the motor and gearbox are from 2019, exhibiting minor surface dirt and wear consistent with regular usage.

The pump is mounted on a metal base equipped with adjustable feet and wheels, simplifying mobility and installation. The stainless steel front housing features two threaded pipe connections. The pump housing is painted blue and shows signs of rust and paint wear, while the stainless steel cover displays minor water spots and slight traces of use but no significant damage. The equipment is currently stored indoors on a concrete floor against a wall.

The Alfa Laval SRU6/260 pump is a reliable choice for demanding industrial applications, combining robust construction with versatile sealing and rotor options, complemented by a high-performance motor and drive assembly.
