Agricultural Application Pumps : Helical Rotor

Cemo borehole and hand-pumps deliver flow rates of up to 120 m3/h. Pumping depths up to 1800m are achievable.

	Hand-operated Pump Simple construction; easy to assemble. Long life; trouble-free operation. Inexpensive maintenance; easily serviceable by unskilled labour. Continuous rotary action delivers steady non-pulsating water flow. No wasted energy; flow rate proportional to pump seed.
	Borehole Pump Easily manages saline, sandy and corrosive water. Above-ground installation except for pumping element. Easy, eye-level inspection of motor and drivehead. High head designs for very deep bores or long distance pumping.
	High-Pressure Horizontal Pump Ideally suited for a variety of water transfer duties. Capacity/flow proportional to pump speed. Developed head independant of pump speed. Inexpensive maintenance; easily serviceable by unskilled labour.
	Submersible Pump Offers savings up to 75% of purchase and installation costs. Accomodates seasonal fluctuations in water table depth without affecting flow. Lower running costs than centrifugal alternatives. Immune to clogging; ideal for domestic use and small holdings.
