FPD FSB-D Close Coupled Low Pressure Chemical Pump

Compact, corrosion-resistant close-coupled centrifugal pump engineered for low-pressure chemical transfer in industrial processes. The single-stage, single-suction horizontal design delivers reliable, low-maintenance pumping for corrosive liquids (acids, alkalis, salts and similar media) across chemical, food, pharmaceutical, paper, water treatment and environmental applications.

Key features

• Close-coupled, single-stage, single-suction horizontal centrifugal construction for a small footprint and simplified installation (no separate coupling or external shaft alignment required).
• Corrosion-resistant wetted materials: polypropylene (FRP), fluoroplastic alloy (F46) or fiberglass, selected to resist chemical attack and minimize material degradation.
• Mechanical seal options: external PTFE corrugated seal or single-end hard-to-hard (silicon carbide vs. silicon carbide) seal designed to operate without cooling water—reducing auxiliary systems and simplifying maintenance.
• Compact and lightweight: low power consumption and easy to handle during installation and service.
• Strong mechanical strength and stable long-term performance: designed to avoid aging or toxic decomposition when handling aggressive media.
• Good sealing and serviceability: seals and components arranged for straightforward inspection and replacement.

Applications

• Chemical processing and transfer
• Corrosive liquid handling in food and pharmaceutical production (as permitted by materials and process requirements)
• Paper and pulp processing
• Water and wastewater treatment
• Environmental and laboratory chemical handling

Selection and ordering guidance

• Confirm fluid compatibility (chemical type, concentration, temperature) with the chosen wetted material (polypropylene/FRP, F46, or fiberglass).
• Specify required flow rate, discharge head, operating temperature range and viscosity to ensure correct pump sizing and motor selection.
• Choose the appropriate mechanical seal type based on media abrasiveness, solids content and whether cooling water is available.
• Provide model number (for example: FP80-32D) and any site-specific requirements (mounting, motor voltage/speed, connection sizes) when requesting quotes or datasheets.

This pump is intended for industrial chemical transfer where reliability, corrosion resistance and compact installation are priorities. For precise sizing and compatibility confirmation, consult detailed pump curves and material compatibility tables with your supplier.
