Tsurumi HSZ2.4S Submersible Trash Pump with Float Switch
The HSZ2.4S combines a compact 0.5 horsepower motor with a built-in float switch for automatic operation. When water rises, the pump activates; when it falls, it shuts off, reducing the need for constant monitoring. It handles water containing sand and solids up to 0.3 inch, with minimal wear and clogging. A 20-foot cord provides flexibility for remote or trailer setups, and the 2-inch discharge port accommodates a range of hoses and fittings for quick hookup on the job site.
Tsurumi HS3.75S Submersible Trash Pump with Agitator
The HS3.75S features a semi-vortex impeller and built-in agitator, enabling debris up to 0.3 inch to pass with less wear and clogging. Powered by a 1 horsepower motor at 115V, it suits demanding dewatering tasks on construction sites or flood cleanup. The pump includes a 32-foot cord for flexible reach and a 3-inch discharge to simplify hose connections and boost productivity in trailer setups or temporary installations.
Tsurumi HSZ3.75S Submersible Trash Pump with Float Switch
The HSZ3.75S integrates a 1 horsepower motor and a 3-inch discharge port, designed for automatic operation via a built-in ball float switch. It’s engineered to pump water containing sand and solids up to 0.3 inch efficiently with minimal wear and clogging. A 32-foot power cord is included, making it a practical option for trailer-mounted or temporary dewatering environments where unattended operation is beneficial.
QFS Mechanical Fuel Pump for Suzuki QuadRunners
This mechanical fuel pump is designed to restore OE performance for specific Suzuki ATV models, ensuring consistent fuel delivery for engine operation. While not a dewatering pump, it represents a trailer-accessible accessory category for off-road or mixed-use setups where engine-driven pumps are part of the system. Potential buyers should verify compatibility with their equipment and consider how fuel-system reliability interacts with portable pumping operations on-site.
AMT® 5585-H6 Self-Priming Trash Centrifugal Pump
The AMT 5585-H6 is engineered for trailer mounting with self-priming capabilities. It uses a cast aluminum body with mixed metal components and a Silicon Carbide/Viton mechanical seal for durability in gritty water. Features include Buna-N O-rings, a check valve, 12V DC electric start, and a built-in check valve to prime quickly up to 20 feet. A built-in tachometer/hour meter helps monitor performance and maintenance on mobile dewatering projects.
Buying Guide: Key Purchase Considerations
- Debris handling: Look for pumps rated for solids up to at least 0.3 inches to minimize clogging in messy water.
- Power and mobility: Trailer-mounted applications benefit from pumps with compact footprints, reasonable weight, and electric start options or float-switch automation for unattended operation.
- Discharge size and fittings: Choose discharge ports (2″, 3″) that match your hoses and truck/trailer plumbing; ensure hoses and adapters are readily available.
- Automatic versus manual: Float-switch-enabled units avoid constant supervision, especially on job sites with variable water levels.
- Cord length and reach: Longer cords facilitate use away from power sources; consider a model with a reliable ground-fault circuit interrupter (GFCI) if used at construction or flood sites.
- Durability and materials: Cast aluminum and corrosion-resistant seals extend life when pumping dirty or aggressive water; check impeller design (semi-vortex vs. vortex) for debris tolerance.
- Maintenance: Self-priming and easy-access seals reduce downtime. Note service availability and spare parts in your region.
- Power source compatibility: Electric pumps work well with generators or fixed hookups; engine-driven options can be beneficial where electrical power is unavailable.
- Overall cost of ownership: Consider initial price, maintenance needs, seal lifespan, and energy consumption over time.
- Application fit: Match pump capacity (GPM) and head (lift) to your dewatering scenario—high flow is essential for flood events; moderate flows suffice on construction sites with large debris loads.
These considerations help ensure you select a trailer-mounted pump that reliably handles debris, operates automatically when needed, and remains efficient across job-site conditions. Always verify compatibility with your specific hoses, fittings, and trailer mount approaches before purchase.
