Self-priming Pumps

(as bilge, ballast and fire-extinguishing pump)

Application

for water containing sand and solid in suspension

for handling liquids corrosive, aggresive with or without solids. The self-priming effect needs no extra device. Foot valve is not necessary.

Used as a bilge-, ballas and fire fighting pump. Dewatering of construction pits draining, injection of well tubes, handling of dirty fuel.

Design

The replaceable wear plate has an abrasion resistant facing and the open impeller has wide passages for handling solids. Many models have inspection-openings. Pump is only available in horizontal, single stage design, some with grease lubricated mechanical seal for short dry running.
