Irrigation
JOYWAY JW-WP520 Petrol Water Pump
The JW-WP520 is a small petrol water pump from JOYWAY, driven by a 52 cc single-cylinder two-stroke engine (reference 1E44F-5) rated at 1700 W. It has recoil start, an 1100 mL fuel tank and a net weight of 14.0 kg. Sizes are offered as 1 inch or 1.5 inches. JOYWAY's sheet covers the engine only: it gives no flow, head or pump curve. To size it for irrigation or water transfer, send your flow and lift and ask for the curve and port drawing for the build you will receive.

Build my procurement briefSend your water duty first
The 52 cc and 1700 W figures tell you about the engine. Irrigation flow comes from the pump curve and your installation. Give JOYWAY the flow you need against the total head of your system and ask for the matching point on the curve. Keep suction lift, delivery height and pipe losses as separate numbers. To read total head and suction lift off a pump curve before you compare offers, use our guide to choosing a petrol engine water pump.
| What you send | What JOYWAY should answer |
|---|---|
| Water source and quality | Describe the source, sand, silt or debris. Ask what water the pump end is built for. |
| Flow and head | State the delivery you need and the pipe route. Request the pump curve and the duty point for your build. |
| Suction side | Give the height from water to inlet, hose length and how you will prime. Ask for the suction and priming limits. |
| Running time | Say how long and how often it will run. Ask for the allowed duty and the service schedule for this engine and pump pairing. |

Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| Pump and engine references | Item Name JW-WP520; Model No. 1E44F-5 [1] | Pump model and engine reference sit in separate rows. Check both plates on the delivered unit. |
| Engine displacement and power | 52 cc; 1700 W as printed [1] | Engine figures only, with no rating conditions. Flow and pressure come from the pump curve. |
| Engine speeds | Idle 3200 rpm; maximum 8000 rpm [1] | Engine speeds, with no matching pump duty point. |
| Engine type | Single cylinder, two-stroke, air-cooled; diaphragm carburettor; C.D.I ignition [1] | Describes the engine. Ask separately for the pump body material and what water it can handle. |
| Starting and fuel | Recoil start; fuel tank 1100 mL; oil ratio 25:1 [1] | Mix fuel to the engine manual for your build. Run time is not given. |
| Size options | Width 1 inch / 1.5 inches [1] | Labelled Width, without saying whether it is inlet, outlet or both, or the thread standard. |
| Weight | N.W. 14.0 kg; G.W. 14.5 kg [1] | Box contents are not listed. Ask what accessories ship with the pump. |
| Pump performance | Flow, head, suction lift and pump curve not published [1] | Request these for the exact build before choosing the pump. |
| Photo label | The linked product photo shows BC430 on the housing [1] [2] | A different code from the pump and engine rows. Ask JOYWAY which code your unit carries. |
What the 1-inch and 1.5-inch options mean
JOYWAY lists the two sizes under Width. The sheet leaves open whether inlet and outlet are the same size, whether these are nominal hose sizes, and which thread or coupling is fitted.
Before buying hose and fittings, request a drawing with inlet and outlet sizes and thread standards shown separately. Ask which couplings, seals and strainer come with each size. For suction hose vacuum ratings and how inner diameter drives friction loss, our guide to specifying irrigation hose and pipe is the companion to that drawing. A wrong suction fitting is much easier to fix on paper than at the water's edge.

Engine code and the BC430 photo label
The table calls the pump JW-WP520 and gives 1E44F-5 as the Model No. A linked product photo shows BC430 on the engine housing, and the site says nothing about how the two relate. The 52 cc figure belongs to the table entry.
Before a sample ships, ask for photos of the pump plate and engine plate on the same unit, a close-up of the ports, and a spec sheet carrying the quoted revision. With that settled, the engine manual for that build covers fuel mixing, starting, priming and running. The table's 25:1 mix ratio should match what that manual says.
Accepting a pump you can test
The engine sheet is one part of the package. Put the pump performance and the connections in the quotation as well. Requesting the same performance and connection details for the ERAYAK EYP Petrol Water Pumps gives you a second quotation to set against it.
Fix the build
Record the JW-WP520 pump plate, engine plate, pump end, port drawing and accessories, with the photo-label question answered.
Agree performance
Get flow and head data for that build and agree how a transfer test will be run.
Check the delivery
Match plates and fittings to the agreed sheet. Note whether the weight and box include hoses or other parts.
Handover
Collect the operating and service manual, spares list, warranty terms and documents your market requires. Ask JOYWAY to state its service response in writing.
Buyer questions
How much water does the JW-WP520 pump?
JOYWAY's table gives no flow, head or curve. The 1700 W engine figure cannot answer it, so ask for the curve for your build. [1]
Is 1 inch or 1.5 inches the inlet size?
The row is labelled Width and does not say which port. Ask for an inlet and outlet drawing with thread standards. [1]
Does the BC430 label mean the engine is not 52 cc?
The site does not explain it. Ask JOYWAY for photos of the pump and engine plates on the unit it will ship. [1] [2]
Can it pump dirty water?
No water-quality or solids rating is published. Describe your source water and ask JOYWAY to confirm in writing which pump end suits it. [1]
