Pumps
Industrial pumps are used for transferring wastewater, water, low-viscosity liquids, hygienic products, and auxiliary process fluids in treatment plants, industrial pipe networks, HVAC systems, marine service, and food, beverage, pharmaceutical, and cosmetic processes. Pump selection should be based on the duty point, flow rate, differential head, NPSH available versus NPSH required, operating temperature, viscosity, solids content, corrosion potential, installation arrangement, and material compatibility with the pumped medium.
S-WN wastewater pumps are intended for dry installation in either horizontal or vertical configuration, with flanged suction and discharge connections. The range covers capacities from 68 to 4000 m³/h with connection sizes from DN50 to DN600. Impeller selection depends on solids loading and clogging risk: channel impellers for higher hydraulic efficiency, B-tween designs where reduced blockage probability is required, vortex impellers for greater free passage, and cutter versions for sewage containing fibrous or bulky solids.
S-WP submersible pumps are used in dry, wet, or portable wastewater installations, with a similar hydraulic range of 68 to 4000 m³/h and DN50 to DN600 connections. Evaluation should include impeller geometry, motor protection, moisture sensors, cooling arrangement, cartridge-type mechanical seal design, and suitability for inverter operation. For the S-WP series, the stated maximum liquid temperature is 45°C, with IE3 IP68 motors and integral thermal protection.
S-IP and S-MP in-line pumps are vertical single-stage centrifugal units for low-viscosity liquids and relatively high flow service in marine systems, HVAC circuits, general industrial utilities, and fire-fighting networks. The stated range is up to 650 m³/h, with DN40 to DN250 connections, ISO 2858 dimensional design, PN10 or PN16 pressure classes, and materials including cast iron and brass, depending on fluid compatibility and service conditions.
S-FP hygienic pumps are used for food, beverage, pharmaceutical, and cosmetic duties, with capacities up to 100 m³/h. They are specified with EHEDG certification, internal surface roughness below 0.8 Ra, CIP capability, an operating temperature range from -20°C to +140°C, and either single or double mechanical seals. Maintenance should focus on seal faces, EPDM or Viton O-rings, impeller wear, wear ring condition, shaft alignment, vibration, noise, leakage control, and verification that the pump operates close to its best efficiency point.
