Hydroseeder – PN-90/4

Hydroseeder – PN-90/4



Slurry tanker PN-90/4 is designed as self-supporting tank, mounted on a double-axle sprung chassis.


A steel, hot galvanised tank with central frame has internal strengthening rings and baffle. Opened rear head with two connection pipes. 3” sight-glasses are mounted on the front head and connection pipes for valves on sides of the tank. A Ø 200 mm hatch, Ø 400 mm quick opened hatch and overflow safety device are placed in the upper part of the tank.


JULIA pumping unit (compressor coupled with impeller pump) is mounted on the drawbar.


A hydraulically controlled 5” gate valve with a spreading spoon and manual gate valve are mounted on the rear head. A 2" connection pipe is mounted on the bottom of the tank, allowing to connect an additional discharge hose, e.g., for crops watering. A three-way valve in the upper part of the tank allows redirecting the liquid stream from the pump onto the gun or onto the ball valve placed on pump's connection pipe.


On request, the slurry tanker can be equipped with a hydraulically driven slow-speed worm stirrer which can stir tank contents continuously.


Tank filling is achieved by vacuum, made in the tank by the compressor, driven by a PTO shaft from the tractor. Tank emptying is done by overpressure or through the gun with the impeller pump, switched by the gear lever to reverse rotation.


Sprinkling can be done in two ways:
a) by the compressor – through the spreading spoon
b) by the impeller pump – through the gun from the upper platform.


The tanker has got a CE declaration of conformity. The approval certificate allows vehicle registration and opens free access to public roads.
