Pressure and Temperature Limits:

• Pump: Pressure and temperature limits for the pump vary by material variant and bearing bracket type (CS or CA). See the official PDF, Fig. 1 and Fig. 2, for detailed diagrams.
• Heating Chamber (heatable version):
  • Version with bolted casing cover: Maximum temperature 150 °C, Maximum pressure 10 bar
  • Version with welded casing cover: Maximum temperature 300 °C, Maximum pressure 20 bar (Not available for sizes CA80, CA85 and CA120)
• Shaft Seals: Application limits depend on circumferential speed, material, and fluid. Consult manufacturer's catalogues for specific operating conditions.
• ASME Flanges: Pressure and temperature limits for ASME flanges (Class 125, 150, 300) vary by material. See the official PDF, Fig. 3 and Fig. 4, for detailed diagrams. For models with ASME flanges, the overall limits are determined by the lowest value from the pump and flange diagrams.

Electrical

Automation options include:

• PumpDrive
• PumpMeter
• KSB Guard

The standard scope of supply includes a surface-cooled IEC frame three-phase squirrel-cage motor.

Mechanical / hydraulic

Design Details:

• Pump casing: Single or double volute (depending on pump size), radially split volute casing with integrally cast pump feet. Replaceable casing wear rings are standard for G/S casing materials and optional for others.
• Shaft seal: Options include gland packing, single mechanical seal, double mechanical seal, and cartridge seal. The shaft is equipped with a replaceable shaft protecting sleeve in the seal area. An alternative "wet shaft" version (without a shaft protecting sleeve) is available in Europe and Northern Asia.
• Impeller type: Closed radial impeller with multiply curved vanes.
• Bearings:
  • Medium Duty: Radial bearing (cylindrical roller bearing), Fixed bearing (paired angular contact ball bearing / double-row angular contact ball bearing).
  • Economy: Floating bearings (deep groove ball bearings).
• Lubrication: Oil lubrication or grease lubrication.

Materials: The pump components are available in various material variants depending on the region (Europe, Northern Asia, Southern Asia, Americas). Materials include different grades of cast iron (CI, DI), unalloyed steel (CS, GP240GH+N / A216 Gr. WCB), stainless steel (SS, 1.4408 / A743CF8M, 1.4308 / A743 Gr. CF8), duplex stainless steel (D, 1.4593 / 1.4517 / A995 Gr. 1B), super duplex steel (SD, Noriclor / 1.4573 / 1.4469.09 / ASTM 995 Gr. 5A), nodular cast iron (JS1030 / A536 60-40-18), and bronze (B, CC480K-GS / -DW / B30 C90700). Specific material combinations for volute casing, casing cover, impeller, shaft, bearing bracket, support foot, seal cover, wear rings, shaft protecting sleeve, and impeller nut are detailed in the official PDF (Tables 6, 7, 8, 9, 10).

Technical Data: Detailed technical data, including impeller outlet width, free passage, impeller inlet diameter, impeller diameter, number of vanes, shaft diameters, and volute casing/hydraulic system design, are provided for each pump size. See the official PDF, Table 12, for exact tabulated values.

Dimensions and Connections: Comprehensive tables list pump dimensions (DN1, DN2, a, b, c, f, g1, g2, h1, h2, m1, m3, n1, n3, n5) and shaft end/pump feet dimensions (d1, l, t, u, y, i1, i2, m2, n2, n4, s1, s2, v, w) in millimeters for all available pump sizes. Connection types and sizes (e.g., G1/4, NPT1/4, Ø 12) for pressure gauges, fluid drains, cooling liquid, leakage drains, barrier fluid, flushing liquid, circulation liquid, oil drain, vent plug, condensate drain, heating medium, quench fluid, vibration measurement, and constant level oiler are also specified, varying by region and discharge nozzle size. See the official PDF, Tables 13, 14, 15, 16, and 17, for exact tabulated values and diagrams.
