Product Description
Direct-connected Water Supply Equipment
Product Overview
The direct-connected water supply equipment is a new type of water supply equipment developed and manufactured by Shanghai Dongfang Pump Industry (Group) Co., Ltd. Adhering to the concepts of technology, environmental protection, energy conservation, and safety, and featuring specialization, refinement, distinctiveness, and innovation, it makes full use of new-generation information technologies such as big data, artificial intelligence, cloud computing, and edge computing. Relying on strong production capabilities, this equipment has remarkable characteristics including high integration, energy conservation and environmental protection, excellent performance, compact structure, and quick installation.
Application Fields
- Pressure boosting for high-rise and multi-storey buildings
- Residential areas with insufficient pressure at the end of the water supply network
- Improving the quality and efficiency of rural drinking water
- Residential areas with old pumping stations undergoing renovation
- Residential areas without pumping stations
- Water supply in scenic areas
- Emergency temporary water supply
Product Features
- Protection Assurance
- The enclosure is made of SUS304 material with a P - shaped rain - proof and sun - proof design (IP55). The exterior is designed with a service life of 50 years.
- Safety and Hygiene
- The food - grade stainless - steel flow - through body operates in a fully - enclosed manner, completely eliminating secondary pollution.
- Energy Conservation and Environmental Protection
- Using pressure - boosting technology with water - squeezing, full - variable control, it makes full use of the pressure in the municipal water supply network, is equipped with air - squeezing pressure, and reduces pressure for small - flow, thus lowering energy consumption.
- Convenient Operation
- One - button start and stop, with a transparent view of the working status. It is designed based on ergonomics, with a compact structure and an aesthetically pleasing exterior.
- Unattended Operation
- Automatic pump switching, balanced operation, automatic inspection, stop when there is no water, and automatic restart when power is restored.
- Intelligent Security
- Remote monitoring, temperature and humidity adjustment, water leakage detection, noise detection, and fault alarm.
- Quick Installation
- Modular detachable structure, pre - fabricated in the factory and delivered as a whole. Just connect the inlet and outlet water pipes and power on to operate.
- Noise Reduction
- Three - layer noise reduction with sound - absorbing panels, integral sound - absorbing covers, and stainless - steel exteriors, which is 10dB or more lower than conventional products.
- Reliable Service
- The company has 16 subsidiaries, 26 branch offices, over 200 business offices, and provides 7×24 - hour after - sales service. The one - time commissioning qualification rate is ≥98%.
