Technical Parameters：

Dingbo Power DB-WP-100 4-Inch gasoline engine water pump is with a flow capacity up to 150m³/h and a pumping head up to 25m, making it ideal for jobsites or farm/agricultural applications.

The DB-WP-100 Difference: Why Buyers Specify This Model

Dingbo Power manufactures engine-driven power equipment from our ISO-certified facility in Nanning, Guangxi, China, with export experience spanning Africa, Southeast Asia, the Middle East, and Latin America. The DB-WP-100 was designed specifically for buyers who need a 4 inch portable gasoline water pump that one person can reposition, one person can start, and one person can operate — without sacrificing the performance that commercial and agricultural applications demand.

① 7-Meter Suction Lift — A Genuine Field Advantage Most competing 4-inch gasoline pumps achieve 5–6m suction lift under ideal conditions. The DB-WP-100 is rated to 7m, meaning it can draw from deeper wells, lower riverbanks, and sunken cisterns that other pumps leave dry. In agricultural regions where water sources are seasonal or irregular, this extra reach translates directly into operational reliability.

② 150m³/h Flow at a Manageable 145kg Weight The DB-WP-100 delivers 150 cubic meters of water per hour — sufficient to irrigate several hectares of cropland, drain a flooded basement within an hour, or supply a mid-size construction site — while remaining light enough for wheeled repositioning by a single operator.

③ Factory-Direct with OEM Capability As a direct manufacturer, Dingbo offers wholesale pricing with no trading company markup, plus private labeling and OEM configuration for distributors entering regional markets.

④ LCD Monitoring Display Standard While competitor models at this size class frequently use analog gauges or no display at all, the DB-WP-100 includes a 2.8-inch 240×128 HD LCD screen for real-time engine and pump status monitoring — a meaningful advantage for extended or unattended operation.

Application Scenarios: Built for the Jobs That Need a 4-Inch Pump

The DB-WP-100's combination of portability, deep suction, and reliable flow makes it the preferred 4 inch portable gasoline water pump across several demanding field applications.

Small-to-Medium Farm Irrigation Deliver up to 150m³ of water per hour to rice paddies, vegetable plots, orchards, and pastureland without any electrical infrastructure. The 7m suction lift allows pumping from seasonal rivers, shallow wells, and drainage ditches that sit well below field grade — a common challenge in agriculture across Southeast Asia, Africa, and South America.

Small Construction Site Dewatering Foundation trenches, utility excavations, and road repair sites frequently accumulate groundwater that must be cleared before work can resume. The DB-WP-100's wheeled rollcage frame and manageable weight allow a single worker to move it between active areas on the jobsite — no forklift, no crew required.

Off-Grid Water Transfer Fill elevated storage tanks, transfer between cisterns, or supply remote water points without relying on grid power or permanent pump installations. At 30L, the fuel tank supports several hours of continuous operation between refueling.

Pond, Canal & Reservoir Management Drain ornamental ponds for seasonal maintenance, manage water levels in aquaculture facilities, or divert canal flow for infrastructure work. The 4-inch bore handles moderate-volume transfer efficiently without the noise and fuel consumption of a larger machine.

Rural Community Water Supply In areas without reliable municipal water supply, the DB-WP-100 can serve as primary or supplementary water sourcing equipment — drawing from shallow wells or natural water sources and supplying storage tanks for daily community use.

Frequently Asked Questions

Q: What is the difference between the DB-WP-100 and the DB-WP-150? 

A: The DB-WP-100 is a 4-inch pump with 150m³/h flow and a 7m suction lift — better for deep-draw applications and situations where portability is important. The DB-WP-150 is a 6-inch pump with 200m³/h flow and a 5m suction lift — better for maximum throughput on large farms or commercial drainage.

Q: Can the DB-WP-100 handle water with light sediment or debris? 

A: The DB-WP-100 is a centrifugal clean-water pump suitable for water with minimal suspended solids. A suction strainer (included in the standard package) should always be used. It is not rated for trash or semi-trash pumping with larger solids.

Q: How long will the 30L fuel tank last at normal operating load? 

A: At moderate load, the 30L tank typically delivers 4–6 hours of continuous operation. Exact fuel consumption varies with head conditions and throttle setting. Full consumption data is available in the technical datasheet on request.

Q: Is recoil (pull-cord) start available as a backup? A: The standard DB-WP-100 uses electric start with a maintenance-free battery. If your application requires a recoil backup start option, please specify this when requesting a quotation.

Q: What certifications does the DB-WP-100 carry? A: Standard export documentation is provided with all units. CE, ISO 9001, and market-specific certification support is available — please specify your destination market when requesting a quote.

Q: What suction hose diameter should I use with this pump? A: 

Use a minimum 100mm (4-inch) diameter suction hose matched to the inlet port. Reducing hose diameter below the pump's inlet will restrict flow and reduce suction performance. Rigid or semi-rigid reinforced hose is recommended to prevent collapse under suction pressure at deep-draw depths.
