PROFESSIONAL THREE-DIAPHRAGM ELECTRIC MOTOR PUMP FOR SPRAYING AND WEEDING

APS 31 Electric

APS 31 Electric is the professional Dal Degan electric motor pump equipped with a three-diaphragm Comet APS 31 pump and a 230 V, 2 HP single-phase electric motor, designed for installation on sprayer trolleys, wheelbarrows, mobile units, pick-up beds, mounted sprayers, and fixed systems. Thanks to its high reliability, maximum pressure of 30 bar, and flow rate of 25 liters per minute, it represents an ideal solution for agricultural, nursery, horticultural, sanitization, and professional landscaping applications. The Comet APS 31 pump features a three-diaphragm configuration, a technology that ensures more uniform delivery compared to traditional twin-diaphragm pumps, reducing residual pulsations and better distributing the workload on internal components. This results in greater operating comfort, less diaphragm wear, quieter operation, and a longer overall lifespan for the pumping unit. The suction and delivery valves are easy to inspect and positioned on the delivery side to simplify routine maintenance. The valve seats and plates are made of stainless steel, ensuring wear resistance and compatibility with the main products used in professional spraying. The pump is connected to the motor via a professional oil-bath gearbox, a construction solution that ensures continuous transmission lubrication, reduces mechanical stress, and helps increase the service life of the entire motor pump unit. The assembly is installed on a sturdy metal base with multiple pre-drilled holes for integration into different types of machines and systems. The 2 HP (2,237 W) single-phase electric motor offers numerous advantages over traditional internal combustion engines: instant start, no fuel required, lower operating costs, reduced noise, simplified maintenance, and zero emissions. For applications in greenhouses, nurseries, warehouses, agricultural facilities, and semi-fixed systems, the electric solution is often the most efficient and economical choice. One of the most appreciated features of the APS 31 Electric is its high versatility. Its performance allows it to simultaneously power:

up to 3 manual lever or knob lances;
up to 2 professional spray guns;
one long-range Mitra spray lance;
a pair of side booms with 3+3 butterfly nozzle configuration for row treatments.

This flexibility makes the unit particularly suitable for vineyards, orchards, greenhouses, nurseries, professional phytosanitary treatments, urban sanitization, and fixed liquid distribution systems. The pressure control unit allows for precise adjustment from 0 to 30 bar. The two standard outlets allow for immediate equipment connection, while the provision for a third outlet further increases operational versatility. The bypass fitting returns unused liquid to the tank, contributing to continuous product mixing and keeping the solution homogeneous during prolonged treatments. APS 31 Electric uses a pump manufactured by Comet S.p.A., an internationally recognized Italian company known for the reliability of its diaphragm pumps and the wide availability of spare parts and technical assistance in the European market.
