Air operated submersible pumps – also known as pneumatic submersible pumps are ideal for those situations when power is not available. They are popular in the mining and construction industries, where they are used for dewatering and sump duties, but are also ideal for water and wastewater pumping or general transfer. Robust cast iron construction and compact design, combined with the ability to pump down to a 22mm level ensures maximum drainage under the harshest conditions and in hazardous or restricted areas. The pump runs completely on compressed air needing no electrical supply. Although the pumps contain an intake filter, if they become blocked with debris, they will simply run dry, without any pump damage.
