Product Description

The Kijito 2008 is a model within the Kijito 2000 series of small wind pumps manufactured by Bob Harries Engineering Ltd (BHEL). Kijito wind pumps are prevalent in the East Africa region and come in a range 8 – 26 ft (2.44 – 7.93 m) of rotor diameters. The Kijito 2000 series is intended to be suitable for small holder farmers, with water sources of about 20 m below ground and who need a limited amount of water for livestock and domestic needs.

Distributions to Date Status

By 2002, approximately 300 windpumps were constructed. An exact number of distributions to date is unknown, however, Kijito design and currently produce about 25 windpumps a year with a capacity to produce up to 50 machines as of 2008.

Pump type

Wind powered pump

Power requirement (W)


Average flow rate (L/min at specific head)

78.47 L/min at 20 m for a 6 m rotor at 4-6 m/s wind speed.

Maximum head (m)

36.5 – 152 m

Diameter (cm)


Design Specifications

The Kijito 2008 windpump transmits power from the eccentrically placed rotor to the pump through a rocker to the pumprods. All rotating components run on ball and roller bearings, which require lubrication twice a year using a vehicle grease gun. The Kijito 2008 model specifications follow: Rotor Diameter: 8 ft (2.4 m) with 12 blades. The models range between 8 – 26 ft (2.44 - 7.93 m) of rotor diameters. Tower: Steel tubular mast with steel rod guides hinged at the tower base. Kijitos are normally supplied on 30 ft (9 m) tripod towers. However extension sections are available as options to increase the rotor height and get better performance. All towers are hinged at their bases to allow easy erection and servicing. This also greatly facilitates access to the borehole when the wind pump is lowered, and reduces borehole and pump maintenance time and costs. Tail: Hinged side vane attached to the transmission via a steel boom providing automatic over speed control by means of yawing activated by the eccentrically placed rotor and hinged vane. Furling: Done by hand with a stop rod on the transmission. Weight: Rotor 50 lbs (22.7 kgs), Transmission 104 lbs (47 kgs), Tower 198 lbs (90 kgs).

Product Schematics

Technical Support

The system can be installed by the customer, using instructions provided, and is transportable in most 1 tonne pick-ups. Alternatively, a foreman can be provided by BHEL to oversee the installation assuming housing is provided.

Replacement Components

The rotor blades can be individually replaced, if damaged for any reason.


The product can function for ~20 years, with proper operations and maintenance, which can be challenging.

Manufacturer Specified Performance Parameters

The pumping yield depend on wind conditions. The manufacturer specifies a 20 ft (6 m) rotor can provide 78.47 L/min at 20 m fat 4-6 m/s wind speed.

Vetted Performance Status

Performance testing has been conducted by the Intermediate Technology Development Group –ITDG (now Practical Action) determining wind pump performance.


No hazards listed by designer.

Complementary Technical Systems

The product can include a 10 ft (3 m) tower extension.
