Piston pumps for domestic water supply
OSNA’s durable and reliable piston pumps are the result of 100 years of experience and expertise in pump manufacturing. We put our first piston pump on the market in 1919. Since then, we have continuously improved the technical basis, performance and durability of our piston pumps and adapted them to the requirements of our customers. Our piston pumps for domestic water supply are now firmly established on the market and enjoy an excellent reputation: OSNA piston pumps sometimes operate for several decades without failure in continuous operation. Our piston pump models are suitable for use in private domestic water supply and agriculture, as well as on board ships.
