]]> Features

This variable speed PID controlled booster system is a sophisticated system, composed of latest technology PID variable speed control cabinet and from two to four sets of parallel pumps. It can be automatically adjusted to fulfil the requirement of constant pressure, variable flow water supply. The pressure of the water supply pipe network keeps constant, and the whole water supply system always keeps the best state of high efficiency and energy saving. There are two types of water supply and the most efficient one is driven by a variable frequency device that automatically adjusts the rotation speed of the pumps; unlike equipment with accumulation or hydropneumatics where pumps start or stop without a demand regulated operation. XBOOST is the best way to keep the pressure of the pipes constant and is very easy to operate and program setting. Many other requirements are available in terms of materials, connection types, accessories, and special features.

Applications

  • Water supply for residential & commercial buildings
  • Garden irrigation
  • Water supply for industrial uses
  • Other boosting applications

]]> Wilo-Atmos GIGA-N https://marineqatar.com/product/wilo-atmos-giga-n/ Tue, 10 Aug 2021 06:52:12 +0000 https://marineqatar.com/?post_type=product&p=3320 The Wilo-Atmos GIGA-N is the entry-level model for glanded pumps. The wide range of motors and materials to choose from plus its wide temperature range from -20 to +140 °C make it a real all-rounder for a whole host of different applications.

Designed specifically for continuous operation, the pump also boasts a long service life thanks to its corrosion-resistant coatings and maintenance-free roller bearings. If maintenance is required, the spacer coupling ensures the mechanical seal can be replaced as quickly as possible. The speed of the Wilo-Atmos GIGA-N is controlled by a Wilo-EFC converter. It can be fitted with temperature and vibration monitoring for the pump bearing so that impending breakdowns can be recognised in good time.

With that in mind, Wilo also offers additional, complementary services ranging from commissioning through to maintenance, and the comprehensive full-service WiloCare package is designed to ensure optimal operational reliability via Wilo remote monitoring.

Your advantages

  • Energy-saving thanks to increased overall efficiency through improved hydraulics and the use of IE3 motors
  • Suitable for drinking water supply (ACS-, UBA- compliant)
  • Cataphoretic coating of all cast components for high corrosion resistance and long service life (not available for the drinking water version)
  • Universally usable thanks to standardised dimensions, a range of motor options and impellers made of different materials
  • Easy maintenance thanks to user-friendly spacer coupling in back pull-out design
  • High operational reliability thanks to improved impeller construction for pressure reduction
