Descaling & High-Pressure Water Jetting

Overview

Scale, rust, and mineral deposits on heat exchanger tubes, reactor walls, pipeline interiors, and industrial equipment are a maintenance reality in Indian process plants. Manual chipping is slow and damages surfaces. Chemical cleaning requires downtime, chemical procurement, and disposal. High-pressure water jetting cuts through deposits fast without surface damage and without chemical hazard.

SEW's Vanguard Series triplex plunger pump generates the sustained high-pressure flow required for effective jetting — 100 to 200 bar at flows of 40–200 LPM — to run jetting lances, rotating heads, and tube cleaning tools continuously across a maintenance shift.

How It Works

Water is fed from a supply tank or direct mains connection through a suction strainer into the triplex pump. The pump raises pressure to the set operating level — determined by the jetting nozzle and required impact force. High-pressure water exits through a flexible hose to jetting gun, lance, or automated rotating head. The triplex pump's three-cylinder design delivers near-continuous flow at stable pressure, avoiding the pressure surges that cause operator fatigue and nozzle wear with single- or twin-cylinder pumps.

Bare Unit Use

Plant maintenance contractors and in-house engineering teams order the bare pump to mount on their existing jetting trolley or skid. Replaces worn pump units in existing high-pressure jetting sets. Flow: 40–200 LPM, pressure: 100–200 bar. Cast iron or SS wetted parts depending on water quality.

Skid Package Use

SEW supplies complete jetting skids: triplex high-pressure pump, motor, V-belt or direct drive, pressure gauge, relief valve, suction strainer, high-pressure hose with gun and lance, water storage tank with float valve — all on a wheeled MS skid for site mobility. Used in: heat exchanger tube cleaning, pipeline descaling, tank cleaning, and surface preparation in steel, chemical, and power plants across India.

Why SEW

100–200 bar sustained pressure — effective scale removal without surface damage. Handles boiler scale, calcium carbonate, rust, and polymer deposits.

Three-cylinder smooth flow — no pressure pulsation. Stable flow reduces operator fatigue and extends hose and nozzle life compared to single-cylinder pumps.

Mobile skid option — complete wheeled jetting set for site maintenance teams. No external pump rental required during planned shutdowns.

Indian manufacturer, Nashik — spare plungers, seals, and valves in stock. Critical for maintenance teams who cannot wait weeks for imported pump parts.
