FLOSITE T-VMS Series: The Compact, Cost-Effective Threaded Vertical Multistage Pump

Introduction: The Space-Saving, High-Performance Solution

Meet the FLOSITE T-VMS Series-the compact and efficient vertical multistage pump specifically designed for small to midsize fixed installations. Featuring practical male threaded connections, this pump is the ideal choice for low to medium-pressure systems, small-diameter piping, and applications where space is at a premium. Built with corrosion-resistant 304 stainless steel wetted parts, it guarantees long-lasting durability. Its hydraulically optimized design ensures high efficiency, and when paired with the optional IE4 super premium efficiency motor, it delivers approximately 3% greater energy savings compared to standard motors. The FLOSITE T-VMS offers reliable, powerful performance in a cost-effective, easy-to-install package.

Ideal Applications: Powering Compact Systems Efficiently

The FLOSITE T-VMS is the go-to pump for smaller-scale commercial, light industrial, and building service applications where reliable pressure and flow are needed without the complexity of flanged systems.

  · Pressure boosting for small to midsize apartment buildings, hotels, and offices.

  · Supplemental water pressure systems.

· Light Industrial & Process:

  · Commercial dishwashers and sanitizing systems.

  · Small-scale parts cleaning and washdown stations.

  · Auxiliary pumps for pharmaceutical, food & beverage applications.

· Water Treatment (Small Scale):

  · Compact reverse osmosis (RO) systems, water softeners, and filtration units.

  · Laboratory or pilot-scale water purification.

· HVAC & Temperature Control:

  · Compact cooling tower make-up, boiler feed, and hot water recirculation.

  · Secondary loops in temperature control systems and heat exchangers.

· Irrigation & Agriculture:

  · Pressurization for greenhouse misting and irrigation systems.

Key Features & Benefits: Designed for Practical Performance

· Compact & Space-Saving Design: With NPT threaded ports and an in-line configuration (suction and discharge on the same axis), this pump requires minimal installation space-no extra room for flange bolts is needed. It's the perfect fit for tight equipment rooms and compact skids.

· Cost-Effective Installation & Operation: The threaded connection system significantly reduces upfront costs for piping and installation labor compared to flanged setups. Combined with the optional high-efficiency IE4 motor, you save on both initial installation and long-term energy consumption.

· Reliable & Durable Construction: All wetted parts are made from 304 stainless steel, providing excellent resistance to corrosion and ensuring a long service life with clean water and compatible fluids.

· Straightforward Installation & Service: Installation is simple using common tools like a pipe wrench. The design facilitates easy access for maintenance when required.

· Robust Performance: Despite its compact size, it delivers high head performance suitable for demanding multi-story applications and handles fluids across a wide temperature range from -30°C to 120°C.
