Water Purification Equipment for Industrial and Municipal Applications — Supplier Guide

Overview

Pump‑centered systems power reverse osmosis (RO), ultrafiltration (UF), pretreatment, and polishing steps in treatment plants and building utilities. These solutions deliver stable pressure, corrosion‑resistant wetted parts, and compact layouts that fit new builds and retrofits.

How These Systems Fit Your Process

Pumping and pressure‑boosting modules keep RO/UF within their operating window. Materials and seals are selected for clean water, slightly corrosive media, and wastewater within pretreatment and backwash lines. Smart controls hold setpoints under varying demand and protect rotating equipment.

Product Lineup

CDLF Stainless Steel Vertical Multistage Pumps

✅Provides the pressure required for RO feed, interstage boosting, and polishing filters.

✅Stainless steel internals support hygiene and corrosion resistance. The vertical design saves floor space.

GDL Vertical Multistage Pumps

✅Suited for filtration trains, circulation, and distribution loops.

✅Compact arrangement with steady pressure delivery in tight plant rooms.

CQ Magnetic Drive Chemical Pumps

✅Sealless magnetic coupling for leak‑free transfer of acids and alkalis in dosing and CIP.

✅Protects operators and maintains consistent chemical delivery.

WQ/QW Submersible Pumps

✅Handles pretreatment sludge and backwash wastewater with solids passage capability.

✅Wet‑well installation options simplify maintenance.

FYS Submerged Pumps

✅For clarified liquids and chemical service in tanks or pits.

✅Minimizes footprint and supports continuous duty.

Intelligent Water Supply and Single‑Pump VFD Units

✅Constant pressure control, soft start/stop, and dry‑run protection.

✅Reduces energy use and limits water hammer to protect membranes and piping.

Key Advantages

✅Energy efficiency and stable performance: High‑efficiency hydraulics and VFD control reduce power draw and hold target pressure. Stable pressure supports consistent flux and membrane life.

✅Compact and easy to install: Vertical configurations and skid‑ready assemblies shorten piping and speed deployment.

✅Materials and hygiene: Stainless steel wetted parts with suitable elastomers. Magnetic drive designs provide leak‑free chemical handling.

Selection Guide

✅Define duty conditions: target flow and head across filters and RO; feed water quality; solids load; temperature; and chemical compatibility.

✅Choose pump types:Vertical multistage for high pressure with a small footprint、Magnetic drive for leak‑free chemical dosing or transfer、Submersible sewage pumps for pretreatment and backwash streams.

Add controls: Apply VFDs and sensors to stabilize pressure and improve energy efficiency.

✅Request a quote: Share RO feed pump duty (flow/head), water analysis, materials/seal preferences, and site constraints.

Integration, Commissioning, and Support

Skid layouts, suction piping, and manifold design are optimized for NPSH and low vibration. Electrical panels and VFDs are tuned during start‑up. Field teams perform installation checks, performance tests, and operator handover. Spare parts and maintenance support are available.

Quality and Customization

Manufacturing follows ISO9001 processes with routine testing. Configure flow/head ranges, materials, seal types, motors, and control packages to match your conditions.

FAQs

Q: How do I size an RO feed pump?

A: Estimate flow from membrane area and target flux. Add a margin for temperature and fouling. Set head to cover membrane differential pressure, piping losses, and elevation. Confirm NPSH and check the pump curve against the operating point.

Q: What materials are suitable for potable service?

A: Use stainless steel wetted parts with elastomers compatible with your temperature and cleaning chemicals. Select mechanical seals matched to water chemistry and thermal conditions.

Q: How does a VFD help treatment systems?

A: It stabilizes discharge pressure, reduces energy use at partial load, and limits water hammer. These benefits can extend membrane and pump service life.
