MODEL 26, 27, 28 Series DRUM HAND PUMP
- Double-action piston pump
- Self priming
- Delivers on the forward and the back stroke
- Less than five cycles yields a gallon (3.8 1)
- All 26, 27, 28 series pumps are made in the same style and have the same action
- Pumps differ in their materials of construction
- Each pump model is constructed using specific polymers and elastomers for resistance to
certain types of chemicals
- Can be used for chemically compatible liquids at temperatures up to 80° F (26° C)
- Viscosity of the liquid should not exceed 2,000 SSU. (about as thick as 40 weight motor
oil at room temperature). Handle effort increases as viscosity approaches this maximum
- Model series 26 and 27 are generally useful with compatible liquids in a mild
acidity/alkalinity range of pH 4-9. Avoid stronger acids and caustics with #26 and #27
series
- Model 28-pumps are useful in a wider pH range.
- Many other chemical characteristics effect the choice of pumps
CHEMICAL COMPATIBILITY OF A PUMP SHOULD BE CHECKED FOR EACH LIQUID BY CHEMICAL NAME. No
one pump can be universally chemical resistant. Some blends of chemicals may not be
suitable for any of these pumps. Several different models may be necessary for several
drums of different liquids. |
