Shipping & Freight

Most equipment and attachments sold by Hardscape Heavy ship by parcel, LTL freight, or specialized freight depending on product size, weight, palletization, and destination.

Commercial delivery locations are preferred when available. Residential delivery, limited-access delivery, liftgate service, appointment scheduling, and other carrier requirements may affect final delivery handling.

Lead times vary by product type, manufacturer availability, selected options, and freight lane. Some configured, special-order, or non-stock items may require additional processing time before shipment.

Buyers should inspect freight shipments at delivery before signing. If visible damage is present, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

The 4-Inch Gasoline Trash Pump is a high-flow dewatering and solids transfer pump built for construction, industrial, and civil jobsites. Powered by a Honda GX630 24 HP engine, it moves up to 2,667 L/min through a 4 in inlet and outlet and passes solids up to 50 mm in diameter — handling muddy water, wastewater, sludge, and debris-laden water that standard clean water pumps cannot manage.

The roll cage frame protects the pump and engine during transport and jobsite handling, and the unit is portable enough to position close to the water source without heavy equipment.

Common Applications
- Construction site dewatering after rain events
- Trench and excavation dewatering during utility work
- Wastewater and sludge transfer on civil jobsites
- Flood response and emergency site dewatering
- Industrial process water and solids transfer

Selection Notes
- Trash pump — designed for water with solids, debris, and suspended material up to 50 mm
- Not suited for clean potable water transfer — use a clean water pump for drinking water applications
- Max flow and head ratings are achieved under ideal conditions — actual performance depends on suction lift, hose length, and solids content
- Honda GX630 engine requires standard gasoline engine maintenance — oil, air filter, spark plug
- Suction hose and discharge hose are not included — contractor supplies hose for application

Flow rate and total head are inversely related — maximum flow is achieved at low head, and maximum head is achieved at reduced flow. Plan pump placement and hose routing to minimize total dynamic head for best performance in dewatering applications.

Pump & Hydraulics
- 4 in (100 mm) inlet and outlet connections
- Centrifugal impeller pump — not self-priming; requires priming before first use each session
- Max flow: 2,667 L/min (705 GPM) at zero head
- Max head: 28 m (92 ft) at zero flow
- Solids passage: up to 50 mm (2 in) diameter through impeller and volute
- Cast iron pump housing and impeller for durability in abrasive water conditions

Engine
- Honda GX630 V-twin gasoline engine
- 24 HP output for sustained high-flow pumping
- 6.1 L fuel tank — runtime varies with load and throttle setting
- Recoil start
- Low oil shutdown protects engine from running dry

Frame & Transport
- Heavy-duty steel roll cage frame — protects pump and engine during transport
- Skid-mounted base for stable flat surface placement
- Lifting point on frame for crane or forklift positioning

Machine Notes
- Prime pump before each use — remove priming plug, fill pump housing with water, replace plug before starting
- Inspect impeller and wear plate periodically for abrasive wear in heavy solids applications
- Winterize pump if storing in freezing conditions — drain all water from pump housing and hoses
- Standard Honda GX630 maintenance schedule applies

Included with Purchase
- 1 4-Inch Gasoline Trash Pump
- Honda GX630 engine (installed)
- Cast iron pump housing and impeller assembly
- Steel roll cage frame
- 4 in inlet and outlet connections

Not Included Unless Stated
- Suction hose and strainer (contractor supplied)
- Discharge hose (contractor supplied)
- Fuel (gasoline)
- Engine oil (check before first use)
- On-site placement or setup labor
