Suction and Discharge Hose
41 products
Showing 1 - 24 of 41 products
Suction and discharge hoses are critical components in dewatering, trash pumping, and industrial water transfer systems. Cleanflow supplies professional-grade suction and discharge hose assemblies designed for construction, municipal, utility, and industrial pumping applications where durability, flow performance, and reliability matter.
This collection includes pump suction hoses, layflat discharge hoses, strainers, and complete hose kits built to handle water containing debris, solids, and wastewater under demanding jobsite conditions.
Common Uses
These hoses are commonly used in applications where water must be moved efficiently using trash pumps, centrifugal pumps, or submersible pumps. Typical uses include:
- Construction site dewatering
- Trash pump suction and discharge lines
- Flood response and water removal
- Municipal and utility maintenance
- Sewage and wastewater transfer
- Industrial water handling and bypass pumping
Types of Suction & Discharge Hose We Offer
Suction Hoses (Pump Inlet Side)
Suction hoses are reinforced to resist vacuum pressure and prevent collapse when drawing water into a pump.
- Reinforced Construction: Spiraled reinforcement ensures the hose maintains its shape under negative pressure.
- Options Available: We carry Tigerflex EPDM and PVC suction hoses, as well as heavy-duty rubber suction hoses for abrasive environments.
- Key Applications: Used on the inlet side of trash pumps and centrifugal pumps.
Discharge Hoses (Pump Outlet Side)
Discharge hoses are designed to carry pressurized water away from the pump. They prioritize flexibility, flow efficiency, and ease of deployment.
- Layflat Design: Lightweight and easy to roll up for storage.
- Variety of Grades: From Single Jacket discharge hoses for general use to the Black Dragon Industrial Layflat, built with a nitrile/PVC blend for superior abrasion resistance in harsh terrain.
- Standard & Heavy Duty: We offer standard Blue and Brown PVC layflat hose assemblies tailored to your durability requirements.
Hose Kits
Trash pump hose kits provide a complete, ready-to-use solution for field operations.
- All-in-One: Includes reinforced suction hose, layflat discharge hose, trash strainer, and camlock fittings.
- Efficiency: Reduces setup time and ensures component compatibility for contractors and rental fleets.

How to Choose the Right Hose
Suction vs. Discharge
- Suction hoses must resist collapse and should never be replaced with lay-flat hose.
- Discharge hoses handle pressure but are not designed for a vacuum.
Solids Handling
Select hose diameters and strainers that allow debris to pass without clogging. Trash pump applications generally require wider internal diameters and reinforced construction.
Hose Diameter & Length
Match the hose diameter to your pump size (e.g., 2″, 3″, or 4″). Keep suction hose runs as short as possible to maintain pump efficiency and prevent cavitation.
Material Compatibility
- Rubber and EPDM hoses for sewage, cold weather, and abrasive environments
- PVC hoses for lightweight, general-duty water handling
Suction vs. Discharge Hose
| Feature | Suction Hose | Discharge Hose |
| Pressure Type | Vacuum (negative) | Pressure (positive) |
| Reinforcement | Heavy spiral (Rigid) | Lightweight jacket or layflat (Flexible) |
| Use Location | Pump inlet | Pump outlet |
| Collapse Resistance | Yes | No |
Brands We Carry
Cleanflow supplies suction and discharge hoses from trusted industrial manufacturers including Greenline, Tigerflex, and other professional-grade hose brands commonly used by contractors and municipalities.
Frequently Asked Questions
What is the difference between a suction hose and a discharge hose?
Suction hoses are reinforced with a rigid helix to prevent collapse under vacuum pressure. Discharge hoses are flexible and designed to handle positive pressure.
Can a suction hose be used as a discharge hose?
While technically possible, it is not recommended. Discharge hoses should never be used for suction.
Why does my suction hose collapse?
Collapse occurs when the hose is not properly reinforced, is damaged, or is too long for the pump’s suction capacity.
What hose works best with trash pumps?
Trash pumps require reinforced suction hoses and heavy-duty discharge hoses. Our Heavy Duty Suction & Discharge Hose Kits are designed specifically for this purpose.
Can these hoses handle sewage?
Yes. Our Tigerflex TG Green EPDM Sewage Suction Hose Assemblies are built for sewage and wastewater applications.
What fittings are compatible?
Most hose assemblies include aluminum camlock fittings. We also stock threaded nipples and strainers compatible with NPT threads.
