Major pump manufacturers are relying on AMPO’s aftermarket service to manufacture complete machined pump components such as impellers, diffusers, suction bells, column pipes, bearing housings, chambers and bowls with really short delivery times.

At AMPO clients can find the most updated know-how and engineering services, including Reverse Engineering and Magma Soft simulations to offer and achieve reliable aftermarket pump solutions.

In the manufacturing of pump components for the aftermarket sector, AMPO implements the latest patternless casting technology in order to obtain high quality castings with dimensional accuracy and improved quality surface finish. With this patternless casting method, ceramic shells are produced in AMPO within a day.

Moreover, once the components are produced, AMPO FOUNDRY has an in-house laboratory and the latest NDT facilities (3D Dimensional Control, X-ray, Dye penetrant tests, magnetic particles, ultrasonic tests, PMI, etc.) in order to ensure the reliability of pump components.

AMPO also offers customized services such as pressure tests, balancing, pre-assembly and painting of components.

AMPO team guarantees a prompt response to customer needs wherever they may be; the organization has a clear orientation towards the development of components with short delivery requirements.  Pump assemblies in West Africa, Middle East, USA, China and India are currently being powered using AMPO components.


Top of the class waterjet manufacturers are relying on AMPO´s latest casting technologies in order to develop critical performance components for waterjets.

Components that were traditionally designed either as sand castings or fabrications are now able to switch to Ceramic Moulding and Shaped Centrifugal Casting processes in order to achieve shorter lead times and improved surface finishes.

AMPO has made significant investments in both processes; last November AMPO opened a new fully automated Ceramic Moulding facility which has increased its Ceramic Moulding capacity up to 240 tons per month and 60 parts a day, quadrupling its previous capacity.

In addition, AMPO has also received a patent for its SCC (Shaped Centrifugal Casting) process, where by using different tools and techniques, complex external geometries and improved casting quality are obtained from centrifugal castings.

Impellers, Housings and Diffusers, along with other marine components are now being manufactured using these processes benefitting from significant cost and quality improvements being obtained including: reduced weights, rapid prototyping / patternless moulding, improved casting integrity and surface finishes.

Diverse vessels including Coast guard, passanger ferry boats and wind farm service boats will be propelled by AMPO components.
