Comet APS 71 Pump

COMET APS 71 high pressure petrol sprayer pump with HONDA GX 270 engine. It features the new three-membrane configuration, guaranteeing outstanding durability and reliability.

This electric sprayer pump with single-phase motor can be applied on carts, wheelbarrows and on trailed or wheeled sprayers.
Flanged pump with petrol engine, speed reducer and control group, mounted on a base.

Suitable for weeding and spraying treatments, medium and small-sized crops, parks, gardens, orchards, greenhouses and for spreading detergents and colours in water solution, washing operations, liquid spraying, etc...


  • N. of membranes / pistons: 3
  • Flow rate: 67.2 l/min
  • Pressure: 40.0 bar
  • Power: 8 hp
  • RPM: 550


If products containing minerals such as kaolin, zeolite, basalt, etc. are used, washing should be carried out at the end of each treatment and at the end of each season to avoid long-term damage to the internal components of the pump. It is advisable to disassemble several parts of the pump, such as valves, heads and diaphragms, in order to clean out any agglomerated residues sedimented by the minerals.
These procedures will ensure a long life of the pump even if the above minerals are used.

Honda GX 270 Engine

Original Honda GX 270 4-stroke petrol engine with 270 cc capacity. It is designed with ”OHV” overhead valve technology. This latest-generation model with OHV technology is suitable for working operations requiring high power.

Many advantages compared to the standard 2-stroke engines (still very popular on petrol sprayer pumps):

Increased reliability, greater ease of starting especially after long periods of inactivity, longer durability, fewer issues related to fuel preparation and freshness, lower fuel consumption, lower nose levels

Heavy-duty connection multiplier in oil bath between engine and pump

Main features:

  • Engine type: 4-Stroke
  • Cylinder type: Cast iron
  • Displacement: 270 cm³
  • Compression ratio: 8.5: 1
  • Max. rpm 3600 rpm
  • Fuel tank capacity: 5.3 L
  • Consumption: 2.4 l/h – 3600 rev/min
  • Dry weight: 25.8 kg

3-way Pressure Adjustment Unit

The heavy-duty pressure regulation unit allows you to adjust the output pump pressure (from 0 to 40 bar) through the upper grey knob. The grey lever with bypass system allows going from low pressure (in which the pump performs a simple water recirculation function) to high pressure for treatments.

The control unit is an original Comet product, GCP standard 3-way series. This consists of 3 available outputs, each equipped with a valve, suitable for many uses.

Generally, the two horizontal outputs are used to connect, for example, a pair of spray guns for orchards / olive groves, or stainless steel bars for vineyard, etc. Instead, the upper central valve is most often used to connect a hose reel or a bulk hose with spraying lances or guns. This operation is carried out directly by the operator.

The black side fitting is the recirculation fitting. In fact, all the liquid that is not used for pumping will come out from that fitting, which must then be connected through a piece of hose to the tank where it is contained. You can also use this overflow to mix the liquid.

Technical Features


  • bar: 0 - 40 (adjustable)
  • flow rate: 67.2 L/min
