Water Supply Equipment

Water Supply Equipment Solutions for Buildings, Industry, and Municipal Use

These pressure boosting systems deliver steady pressure and clean, reliable water for domestic supply, HVAC make‑up, process transfer, and distribution zones. Packages integrate VFD control with high‑efficiency vertical multistage pumps for energy savings and long service life. Each unit can be tailored to required flow, head, and wetted materials.

How Constant Pressure Systems Work

A VFD with PID control adjusts pump speed to keep outlet pressure stable as demand changes. This cuts energy use and helps reduce water hammer. Compact, skid‑mounted assemblies include a control panel, pressure sensing, isolation and non‑return valves, and a stainless steel multistage pump for fast integration.

Core Packages

Single‑Pump VFD Unit

✅Constant‑pressure operation with soft start and stop.

✅Typical ranges: flow up to 120 m³/h, head up to 220 m, setpoint 1–10 bar.

✅Power 0.75–55 kW; common voltages 380–460 V, 50/60 Hz.

✅SS304 or SS316 wetted parts; EPDM or Viton elastomers; panel protection IP54–IP55.

Multi‑Pump Booster Sets

✅2–4 pumps with PLC control, duty/assist/standby logic, and staged VFD operation.

✅Designed for redundancy and stable pressure across wide demand swings.

✅Options include auto changeover, remote monitoring, and dry‑run protection.

Pump and Material Options

Choose CDLF stainless steel vertical multistage pumps for potable and mildly corrosive media. Select GDL vertical multistage models where high head and compact footprint are required. Seal sets are available for site chemistry, with SS304/SS316, EPDM, or Viton selections.

Key Features

✅Stable pressure with fast‑response sensing and refined PID logic.

✅Energy efficiency through speed regulation and optimized hydraulics.

✅Hygienic, corrosion‑resistant construction for potable service.

✅Factory testing under ISO9001; units ship calibrated and ready to commission.

Applications

✅Municipal and community pressure zones with telemetry and alarms.

✅Commercial buildings: domestic water and HVAC make‑up.

✅Chemical and pharmaceutical process and utility water.

✅Power plants and industrial cleaning with adjustable pressure setpoints.

Selection Guide

✅Define peak and average flow, total dynamic head, and pressure setpoint.

✅Confirm water quality and material compatibility.

✅Consider redundancy needs and available footprint.

✅Choose control modes: constant pressure for domestic service, constant differential pressure for HVAC loops, or fixed‑frequency bypass for contingency.

✅Integration options: Modbus/RS485, BACnet gateway, remote monitoring, and pressure tanks for peak shaving.

✅Request pump curves and configuration proposals when finalizing a design.

FAQ

Q: What materials are recommended for potable water?

A: SS304 or SS316 wetted parts with EPDM elastomers are typical. Confirm with local codes and site chemistry.

Q: Can these packages integrate with building automation?

A: Yes. Systems can provide Modbus/RS485 and, with a gateway, BACnet for monitoring and alarms.

Q: How do multi‑pump sets improve reliability?

A: Duty/assist/standby logic and auto changeover maintain service if a pump is offline and optimize efficiency across load changes.
