Choosing a sizeOne model per quotation [1] [3]Pick the size that fits your flow and lift, then quote that single build.

Rated and maximum flow and head by size

Each ERAYAK page gives two sets of figures. The maximum flow is reached at low head and the maximum head at low flow, so the two maxima mark opposite ends of the curve. The rated entry is the practical working point. For example, the 3-inch pump lists 33m³/h at 17m. Size your pump on the rated figures and ask Leiya for the full curve to check your own duty point. Our guide to sizing a petrol water pump for irrigation explains total head and suction lift, the two numbers you need to place that duty point.

Pump sizeMaximum figures and rated point
2-inchMaximum 30m³/h flow and 32m head; rated 24m³/h at 19m
3-inchMaximum 48m³/h flow and 30m head; rated 33m³/h at 17m
4-inch upgradedMaximum 86m³/h flow and 28m head; rated 56m³/h at 15m

Matching the pump to your water source

Before you ask for a price, write down the flow you need at the outlet, the height from water level to discharge, how the suction side is set up, the hose length and fittings, and what the water carries. Leiya can then send the curve and state the solids size, water temperature and suction lift the pump accepts, along with the right strainer and connections. Hose choice changes friction loss too; our irrigation hose specification guide covers suction and lay-flat hose. For a second quote, compare the JOYWAY JW-WP520 Petrol Water Pump from another maker.

The pages call these pumps self-priming. In practice that means you fill the pump housing with water before the first start; plan for an operator to do this on site.

The upgraded 4-inch has a larger engine and fuel tank than the 2-inch and 3-inch pumps. The catalogue gives no fuel use or run time, so ask for both, together with the operating limits and who services the engine and the pump.

Container quantities for the 3-inch EYP80

In the 2026 catalogue the EYP80 ships in a 545 × 430 × 440 mm carton, with 280 units per 20GP, 565 per 40GP and 678 per 40HQ. The 3-inch web page gives 580 per 20GP for the same carton. Ask Leiya for a load plan with dimensions that states the real quantity for your container.

Carton sizes and weights change with the engine and port size, so list the accessories and protective packing you expect in the order schedule. Use the row for the exact model you buy when planning freight.

Model codes, manuals and certificates

Leiya sells this range as EYP50, EYP80, EYP100A, EYP100B and EYP150 in its 2026 catalogue, while the live 2-, 3- and 4-inch pages switch to an EYG code in their overview paragraphs. Get the code written on the quotation and make sure the nameplate and parts manual carry the same one.

Leiya's download page offers generator and ATS manuals, and its certificate files are filed under generators. Request the pump manual and the conformity papers for the configuration you order.

Buyer questions

Will the EYP80 deliver 48m³/h at 30m head?

Those are two separate maximums from opposite ends of the curve. The rated point is 33m³/h at 17m. Ask Leiya for the curve to read the flow at your head. [3]

Which size should I order for irrigation?

Start from the rated figures. The 2-inch gives 24m³/h at 19m, the 3-inch 33m³/h at 17m and the upgraded 4-inch 56m³/h at 15m. Pick the one that covers your flow at your lift. [2] [3] [4]

How many 3-inch pumps fit in a 20GP container?

The catalogue says 280 and the web page says 580, both for the same carton. Ask Leiya for a load plan that confirms the number for your order. [3] [5]

Are these pumps truly self-priming?

Fill the pump housing with water before the first start. Ask Leiya for the suction lift limit of your model. [2] [3] [4]
