Pompe centrifuge industrielle à arbre nu — 4CA 200-315B
-
OPTIMIZED FOR COOLING SYSTEMS: The 4CA200-315B bare shaft centrifugal pump is built to EN 733 standards, delivering consistent water flow and reliable pressure for demanding cooling systems applications.
-
LOW-SPEED EFFICIENCY & MOTOR READY: Operates at a quiet 1450 rpm for reduced wear. Designed for easy flexible coupling with standard electric or high-efficiency IE3 motors, reducing long-term power costs.
-
RUGGED DURABILITY: Features a heavy-duty cast iron pump body, a robust cast iron seal plate, and a high-grade AISI 316 stainless steel shaft end to withstand intense daily use.
-
FLEXIBLE IMPELLER OPTIONS: Comes standard with a cast iron impeller, with optional upgrades to bronze or stainless steel for enhanced corrosion resistance and specialized liquid handling.
-
WIDE OPERATING RANGE: Safely handles clean liquids at temperatures ranging from -10°C to +90°C and sustains operating pressures up to 10 bar, providing versatile performance.
Informations sur le produit
The Pentax 4CA200-315B is a heavy-duty, bare shaft horizontal centrifugal pump end engineered in strict compliance with EN 733 European standards. Specifically built for cooling systems, it provides supreme hydraulic durability.
Designed as a bare shaft pump unit (without motor), the 4CA200-315B connects via a flexible coupling to standard 4-pole electric motors (including high-efficiency IE3 motors) or diesel engine drivers. It features a DN150 suction port and DN200 delivery port, delivering maximum hydraulic efficiency at operating pressures up to 10 bar.
Engineered for long-term continuous operation, the pump incorporates a heavy cast iron casing, cast iron seal plate, AISI 316 stainless steel shaft end, and a 70 mm ceramic-graphite-NBR mechanical seal. Handling fluid temperatures from -10°C to +90°C, the Pentax 4CA200-315B offers versatile customization options with cast iron, bronze, or AISI 316 stainless steel impellers, as well as gland packing seal upgrades.
Impeller & Configuration Comparison:
Cast Iron Impeller (Standard): Economical choice for clean water and standard daily industrial pumping.
Bronze Impeller (Optional): Eliminates rust seizure during long standby periods (ideal for fire pumps) and provides exceptional resistance to sea water and cavitation.
Stainless Steel AISI 316 Impeller (Optional): Maximum chemical, acid, and abrasion endurance for harsh industrial liquids.
Gland Packing (Optional): Traditional braided rope packing alternative to mechanical seals for high-sand or slurry environments.
Note: Bare shaft pump only. Motor, coupling, baseplate, and optional counter-flanges sold separately.
