DEPA® Series DP
Powder Series DEPA® Diaphragm Pump
The largest Air-Operated Diaphragm Pump in the world (DP 125) with a flow rate of up to 2400 kg (5291 lb/h) at a bulk weight of 60 g (0.1 lb)/l, was developed and manufactured by Crane in cooperation with process industry partners.
Until now, no other pump type has been able to fulfill the specific task settings of the industry in an economical and functional way.
All DEPA diaphragm powder pumps are fitted with specially formed suction and discharge manifolds for favorable flow conditions.
The high flow rate is achieved by good fluidisation of the products. Regarding the discharge of granulates and crystalline media, special requirements have to be met.
Various materials for body, diaphragms, valve seats and valve balls are available.
Features and Benefits
- DEPA powder pumps are portable and mobile.
- Low product velocities, compared with other methods of powder pumping, result in gentle product handling.
- Lower cost and more efficient powder transfer than mechanical methods.
- Because of the low air to product ratio (typically 1:3 to 1:5), less air need be extracted on the discharge side.
