Water Suction Hose 150PSI / 250PSI

Product Overview

The Water Suction Hose 150PSI / 250PSI is a high-performance rubber hose engineered for reliable suction and discharge of water and non-corrosive fluids in demanding construction and industrial environments. As a professional china-based manufacturer, we define this product as a hardwall, lightweight, and flexible hose that meets global standard requirements for rugged applications. Whether you need a Water Suction Hose for dewatering, slurry transfer, or general site drainage, this hose delivers consistent performance under tough operating conditions.

Constructed with a black smooth NR/SBR rubber tube, high-strength synthetic fibre and helix steel wire reinforcement, and a weather-resistant SBR rubber cover, this rubber hose offers exceptional durability. Key parameters include a working pressure of 10 bar (150 PSI) or 17 bar (250 PSI), a burst pressure of 30 bar (450 PSI) or 51 bar (750 PSI), and a vacuum rating of 0.8 bar. The temperature range spans from -30°C (-22°F) to +80°C (+176°F). Core advantages include weathering and ozone resistance, an anti-aging cover compound, and a lightweight, flexible design. Primary applications include construction sites, light-duty industrial water transfer, dewatering, suction for pumps, and agricultural irrigation. This Water Suction Hose directly solves common site problems such as hose kinking, cover cracking under sunlight, heavy weight causing worker fatigue, and burst risks during pressure spikes. As a trusted supplier, we back every hose with strict quality control and optional third-party certification.

Structure and Materials

• Tube: Black, smooth NR (Natural Rubber) and SBR (Styrene-Butadiene Rubber) compound. Provides excellent resistance to water and mild chemicals while ensuring low flow resistance.
• Reinforcement: Multiple plies of high-strength synthetic fibre plus a helix steel wire. The helix wire prevents kinking and collapse under vacuum, while the synthetic fibre plies provide pressure containment.
• Cover: Black, smooth, cloth impression finish, SBR rubber compound. This outer layer is formulated for weathering, ozone, and abrasion resistance. The cloth impression improves grip and reduces surface damage during dragging.

Why Helix Steel Wire + Fibre? Unlike a standard Wire Braided Hose or Wire Spiral Hose designed for high-pressure hydraulics, this suction hose uses a helix wire as a rigid骨架. The helix steel wire acts like a spring coil, maintaining the hose’s round cross-section under strong vacuum (0.8 bar). Without this wire, a standard rubber hose would collapse when the pump pulls water. The synthetic fibre plies then contain the positive pressure up to 250 PSI. This hybrid design makes our Water Suction Hose both a suction and discharge hose.

Deep Technical Insight – Why Not Use a High Pressure Hose for Suction?

A High Pressure Hose like 4SN or R13 is designed to contain internal pressure but has very low resistance to external collapse. Under vacuum, the inner tube of a High Pressure Hose will collapse inward, blocking flow. Our Water Suction Hose is specifically engineered with a rigid helix wire to resist collapse at -0.8 bar vacuum. This is a critical distinction for engineers designing pump inlet lines.

Application Industries

Primary Application Scenarios

• Construction Sites: Dewatering excavations, transferring water from ponds, and supplying water to onsite equipment.
• Municipal Works: Sewer bypass pumping, stormwater drainage, and tanker truck loading/unloading.
• Agriculture & Irrigation: Suction from rivers or canals, feeding irrigation pumps, and liquid manure transfer.
• Industrial Plants: Cooling water supply, sump pump discharge, and non-corrosive fluid transfer.
• Mining & Quarries: Light-duty water removal and dust suppression systems.
• Marine & Shipyards: Bilge pumping, deck washing, and temporary water supply lines.

Precise Selection Professional Guide

1. Hose Assembly Solutions

A bare hose is only half the solution. We offer complete hose assembly services using crimped fittings, reusable fittings, adapters, and flanges. Our in-house Assembly process includes:

• Crimped Fittings: Permanent, leak-free connections for highest reliability.
• Reusable Fittings: Field-attachable, ideal for emergency repairs.
• Adapters: Convert between BSP, NPT, or camlock threads.
• Flanges: For large-diameter (4” to 14”) bolted connections.
• Protective Sleeves & Guards: Abrasion-resistant protective sleeves and guards extend hose life when dragged over concrete or sharp edges.

Why Factory Pre-Assembled? Our factory Assembly ensures correct insertion depth, crimping force, and 100% pressure testing – reducing field failure risk by over 80% compared to field-assembled connections.

3. Solving Common Site Pain Points

• Pain Point: Hose covers crack after 3 months in sunlight.
  • Our Solution: Anti-aging SBR cover compound with weathering and ozone resistance – tested for 500+ hours UV exposure without cracking.
• Pain Point: Hose kinks and collapses under pump suction.
  • Our Solution: Helix steel wire reinforcement maintains full round shape even at 0.8 bar vacuum.
• Pain Point: Heavy hoses cause worker injuries.
  • Our Solution: Lightweight NR/SBR construction – up to 30% lighter than all-rubber suction hoses of same ID.

Technical Standards and Certifications

Our Water Suction Hose 150PSI / 250PSI is manufactured according to international norms:

• Standard: Designed to meet or exceed ISO 1307 (hose ID tolerances) and EN 1765 (suction hose performance).
• Safety Factor: 3:1 minimum burst to working pressure (exceeds many generic hoses).
• Certifications Available: ISO 9001:2015 quality management system. Optional third-party inspection (BV, SGS) can be arranged.

Brand and Quality Assurance

As an experienced china manufacturer, producer, and factory, we control every step of production. Our quality assurance includes:

• Raw Material Incoming Inspection: Each batch of rubber, steel wire, and synthetic fibre is tested for tensile strength, hardness, and adhesion.
• In-Process Control: Tube extrusion, spiral winding, helix wire placement, cover extrusion, and vulcanization are monitored real-time.
• 100% Factory Testing: Every finished hose length undergoes a hydrostatic test at 1.5x working pressure for 5 minutes – zero leakage required.
• Lab Testing: Burst testing, vacuum collapse testing, ozone resistance (ASTM D1149), and accelerated aging (ASTM D573).

Third-Party Validation: We offer downloadable pdf test reports from accredited labs, including burst pressure curves and vacuum collapse data.

Customer Case: A Singapore-based construction company switched to our 150 PSI Water Suction Hose for site dewatering. They reported a 60% reduction in hose replacement frequency and zero vacuum collapse incidents across a 12-month period.

Installation, Operation, and Maintenance Guide

• Installation: Always use properly sized fittings (camlock, BSP, or NPT). Avoid sharp bends – minimum bend radius is 10x hose OD. For suction lines, keep the hose as straight as possible before the pump inlet.
• Operation: Never exceed the maximum working pressure (150 PSI or 250 PSI). Do not use for petroleum fuels, acids, or solvents. The temperature limit is -30°C to +80°C.
• Maintenance: Inspect the cover regularly for cuts or abrasion. Clean with water and mild soap. Store in a cool, dry place away from ozone sources (motors, transformers). Replace if cover is deeply cut or if the helix wire is exposed.

Frequently Asked Questions (FAQ)

Q1: What is the difference between Water Suction Hose and a standard High Pressure Hose?

A: A High Pressure Hose (like Wire Braided Hose or Wire Spiral Hose) is designed to contain internal pressure but will collapse under vacuum. A Water Suction Hose contains a helix steel wire that resists collapse at -0.8 bar, allowing it to both suck and discharge water.

Q2: Can I use this hose for hot water?

A: The maximum temperature is +80°C (+176°F). For higher temperatures, please consult our support team for a different solution.

Q3: Do you offer custom lengths?

A: Yes. Standard lengths are 20m, 30m, 40m, 60m, 100ft, and 200ft. Bulk rolls (up to 200m) and cut-to-length service are available.

Q4: What is your MOQ and lead time for bulk orders?

A: MOQ starts from one 60m roll for stock sizes. For wholesale and bulk orders (1000m+), lead time is 15-25 days. Discount available for volume purchases.
