FLOSITE VMS Series: The Definitive Stainless Steel Vertical Multistage Pump
Introduction: The FLOSITE Standard for Demanding Applications
Introducing the FLOSITE VMS Series-a benchmark in vertical multistage pump engineering, crafted to deliver exceptional performance across commercial, agricultural, and industrial sectors. Designed with a robust cast iron flange and precision-crafted 304 stainless steel impellers and diffusers, this centrifugal pump guarantees superior corrosion resistance and long-term durability. We’ve re-engineered the hydraulic core for peak hydraulic efficiency and simplified the mechanical design for maintenance-free service-no special tools are needed for assembly or disassembly. To maximize your operational savings, pair it with an optional IE4 super premium efficiency motor, delivering approximately 3% more energy savings than standard models, making the FLOSITE VMS a smart, energy-efficient pump investment.
Versatile Applications: One Pump, Endless Solutions
The FLOSITE VMS pump is engineered to be the heart of your system. Its reliable and adaptable performance makes it the ideal choice for:
· Water Supply & Pressure Boosting:
· Building water pressure boosting for hotels, high-rise apartments, and commercial complexes.
· Booster pump stations and municipal water supply networks.
· Pressurization units for residential and industrial water systems.
· Water Treatment & Filtration:
· Reverse Osmosis (RO) system feed and booster pumps.
· Ultrafiltration (UF) systems and deionization plants.
· Water softeners, desalination units, and distillation systems.
· Light Industrial & Process:
· Industrial wash-down and cleaning systems (parts cleaning, vehicle wash tunnels).
· Commercial dishwashers and food processing lines.
· Fire protection system pumps (jockey/ pressure maintenance pumps).
· Pharmaceutical, food & beverage applications requiring hygienic standards.
· Irrigation & Agriculture:
· Greenhouse irrigation and misting systems.
· Agricultural field irrigation and water transfer.
· HVAC (Heating, Ventilation & Air Conditioning):
· Cooling tower circulation and chilled water systems.
· Boiler feed, condensate return, and hot water recirculation.
· Temperature control systems and heat exchangers.
Core Features & Benefits: Engineered for Excellence
· High Head & Large Flow Performance: Achieve demanding system requirements with a pump head up to 260m and a flow rate up to 160 m³/h, providing powerful and consistent fluid transfer.
· Superior Energy Efficiency: Our optimized hydraulic design reduces internal losses. The optional IE4 motor takes savings further, significantly cutting electricity costs and operational carbon footprint.
· Robust Construction for Long Life: The combination of sturdy cast iron pump flanges and all 304 stainless steel wetted parts ensures maximum resistance to corrosion and wear, guaranteeing a long service life even with demanding media.
· Wide Operating Range: Handle clean, thin fluids across a broad temperature range from -30°C to 120°C, making it suitable for near-freezing water to hot circulation duties.
· High-Pressure Capability: Built to withstand rigorous conditions with a maximum working pressure of up to 16 bar or 25 bar (depending on pump model and flange configuration).
· Easy Installation & Maintenance: The in-line port design (suction and discharge on the same horizontal axis) allows for compact, straightforward piping. The user-friendly mechanical design enables quick inspection and servicing without any special tools, minimizing downtime and labor costs.
