• Other materials upon request.

Mechanical / Hydraulic

Design Variations

• Design LS: Horizontal single-stage end-suction pump with closed impeller and oil-lubricated bearing frame. Process design with back pull-out for easy maintenance. Suction branch axial, discharge radial upwards (optional horizontal).
• Design LSV: Vertical design with short shaft for dry installation. Bearing frame with grease-lubricated antifriction bearings.
• Design LT: Vertical line shaft version. Bearing frame and motor above pit for dry installation. Pump end flooded by the handled liquid. Radial friction bearing lubricated by handled liquid or with external clean water lubrication. Installation length up to 10 m.
• Design LC: Foot-mounted casing design for operating temperatures up to max. 180°C (350°F) / 25 bar (360 psig).
• Design LCP: Process design with centerline casing feet for operating temperatures up to max. 210°C (410°F) / 25 bar (360 psig). Centerline casing feet and additional support feet prevent negative influence on coupling alignment from thermal expansion at high operating temperatures. Oil sump cooling of bearing frames is required above 180°C (350°F).

Design Features (LS, LC, LCP)

• Horizontal single-stage end-suction pump with closed impeller.
• Process design, back pull-out for easy and safe maintenance. Disassembly of impeller and bearing frame without dismantling pump casing and motor (spacer type coupling required).
• Thrust bearing at drive side (pair of angular contact bearings) for high load capability in both directions, roller bearing at pump side.
• Solid shaft dimension for low shaft deflection and heavy-duty oil-lubricated bearings for continuous operation.
• Stainless steel version in dry shaft design, shaft and threads protected by closed impeller nut and shaft sleeve.
• Distance between bearings is greater than impeller overhung.

Shaft Sealing (LS, LC, LCP)

• Stuffing box optional with internal or external flush for temperatures up to 140°C (280°F).
• Stuffing box with cooling jacket for temperatures up to 180°C (350°F).
• Mechanical seals according to EN 12756 (DIN 24960): inner single mechanical seal, double mechanical seals, or cartridge seals.
• Single balanced mechanical seal in "dead end" configuration for hot water applications.
