Mixed Flow, Volute Casing Pump SPL 20024...40056 TECHNICAL DATA Output: Delivery head: up to 1800 rpm depending of the pump size Medium temperature: Casing pressure: Shaft sealing: stuffing box or mechanical seal Flange connections: clockwise, when seen from the drive on the pump APPLICATION Series SPL volute-casing pumps can be used where the requirement is for pumping clean, turbid or slightly contaminated liquids. Occasional solid contaminations can be handled without affecting the pump due to the large internal cross sections. The SPL pumps are suitable for the following applications pumping raw water in waterworks Drive end--ball bearing to DIN 625 or two angular contact ball bearings in an X arrangement to DIN 628. as seawater pumps in desalination plants as coolant pumps in power stations and steelworks for pumping low-concentration cellulose suspensions DESIGN The SPL is a horizontal, single stage, end suction pump flanged to a bearing pedestal. The volute casing has integral support feet and is fitted with a replaceable wear ring. Wearing parts can be removed from the drive end without disturbing the volute casing and pipework. An open impeller (designation A-I) is fitted as standard but a closed impeller (designation K-S) for pumping liquids containing abrasive solids can be fitted if required. Bearings are oil lubricated. Shaft sealing: A stuffing box or a mechanical seal, as required, can affect the sealing of the shaft. Variants with stuffing box: Designation 041: Self-sealing, uncooled stuffing box Temperature range: -10 ºC to 110ºC. Designation 052: Uncooled stuffing box with external sealing and flushing liquid Temperature range: -10ºC to 110ºC. Variants with mechanical seal: The installation with mechanical seal to DIN 24960 is possible in all versions described there, as a single mechanical seal. Temperature range: -10 ºC to 110ºC CONSTRUCTION Casing pressure: between -10 ºC and +110 ºC Flanges: Connection dimensions of flanges DIN 2532 PN 10. Pump end--ball bearing to DIN 625 or cylindrical roller bearing to DIN 5412. as rainwater pumps in sewage works Branch positions: Suction branch axial, discharge branch tangentially upwards. Maximum pump pressure [bar] (4B) 4,0 4,5 Unbalanced single mechanical seal, Materials: 1.4401-carbon-Viton Designation BK3: Unbalanced single mechanical seal, Materials: Carbon-SiC- EPDM Designation BKS: Unbalanced mechanical seal Materials: SiC-SiC-Viton Designation AF3: Balanced single mechanical seal, Materials: Carbon-SiC- EPDM Designation AFS: Balanced single mechanical seal, Materials: SiC-SiC-Viton Double mechanical seals can be mounted on request Note: Casing pressure = Inlet pressure + head at closed valve.
