Sprinkler truck
1. Sprinkler technology: garden sanitation sprinkler adopts automatic production line tank production process, automatic welding of splicing plate, head spinning moulding, tank body once rolling moulding and other domestic advanced production technology. The tank material is made of high quality carbon steel plate.
2. Sprinkler water pump: garden sanitation sprinkler adopts imported technology of high-power special sprinkler pump, can be
Self-absorption and self-discharge, effectively prevent the pumping time is too long on the pump caused by heating and thus affecting the use of life.
Life. The use of water pumps in the process of failure (no man-made damage causes) of the pump I plant to take
Within one year with the old pump for a new pump measures.
3. Sprinkler accessories: the extraction box, ball valve are selected national stereotypes of products, good performance, reliable work, high pressure when sprinkling, ball valves, and so on.
Reliable, high pressure, high flow, low fuel consumption when sprinkling, sprinkling open the music Loudspeaker switch, good music accompanies you to work happily.
When sprinkling, open the music Loudspeaker switch, the good music accompanies you to work happily; power take-off device, this power take-off device can not be affected by the parking, can continuously and uninterruptedly to the external power output, and does not affect the vehicle’s manoeuvrability, with the use of reliable, safe and convenient and other advantages.
