Sigma K2 Hand Pump
$299.00
The Sigma K2 is a double acting semi-rotary hand wing pump. The simple robust design of the Sigma K2 incorporates quality materials and workmanship to guarantee a long and effective service life. The body of the Sigma K2 is cast iron, the wing piston assembly and suction divider are brass and the shaft is steel.
Features of the Sigma K2 Hand Pump:
- The inlet flange, outlet flange, and mounting lugs are reinforced to prevent breakage
- Automatic settlement of the wings is assured by the unique tapered internal body design
- Each pump is tested to a suction lift of 7 meters of water and 20 meters of discharge head
- A drain plug allows water to be drained if the unit will be unused for extended periods of time, or if there is a risk of freezing
- Can handle fluids up to 80 degrees C (176 degrees F)
Applications of the Sigma K2 Hand Pumps:
- Transfer of clear light fluids in the marine, petrochemical, construction, agriculture and automotive industries
- Use in locations where there is no electricity
- A reliable back-up to an electric pump in case of power failure
- Pull water through a submersible pump (see diagram to left)
- Pressurize a tank so there is water at the taps
Operation of the Sigma K2 Hand Pump:
The handle moves back and forth in a 110 degrees arc, which in turn causes the wing piston with flap to semi-rotate within the body.
The suction divider with flaps operates as the inlet check valve.
The pump discharges fluid on both strokes of the handle.
The pump must be bolted to a strong vertical surface with the 2 mounting lugs provided.
The handle can be installed either pointing up, down, left or right.
Note: Sigma pumps that are used for water must be protected from rust whenever they will be unused for extended periods of time. Cooking oil, glycerine or mineral oil is nontoxic and can be pumped through the unit via the drain plug for this purpose.
