Dear clients and users,
We inform you that for reasons beyond Drotec and internal to CRANE, the latter has unilaterally arranged the temporary cessation of the Distribution of valve lines granted to Drotec in June 2024.
We will keep you informed about the evolution of Drotec's valve supply.
We share our new Industrial plant located in the Berazategui Industrial Park. The project began in 2015 with the vision of a new warehouse that would allow us to fully develop our lines of equipment and accessories for the safe and reliable pumping of industrial fluids.
The new plant has 1600 m2 built between factory, workshops, dining rooms and changing rooms.
The plant has a new test pit, with control and report boards and sensors, to be able to test our equipment with maximum reliability.
We share our institutional video.

Since 2006 Drotec distributes in Argentina the M Pumps magnetic coupling pumps manufactured in Italy.
𝙈 𝙋𝙪𝙢𝙥𝙨 offers a very varied range of hermetic pumps without centrifugal losses, regenerative turbine pumps and positive displacement pumps with sliding vanes. They are available in both metal and plastic versions.

The main applications are: pumping of acids and bases, hydrocarbons, thermal fluids, aggressive liquids, radioactive, explosives, toxics and any other application in which it is desired to handle “difficult” fluids WITHOUT losses or emissions and WITH total safety.
In Drotec We know that maintaining an optimal stock of equipment and spare parts is a fundamental factor in providing our customers with quality service, and that is why we have a large stock of magnetic coupling equipment and spare parts. In addition, we test all equipment before leaving the plant and we have an official repair service in the plant.
In DROTEC We manufacture and design each of the parts that make up our pumps, once machined they go to the assembly sector and from the latter they leave for our test bench. In the operation test we guarantee correct compliance with the service requested by the client, comparing the performance of the pump with the characteristic curves.
This bench has a frequency converter, energy meter, pressure sensors, control software and other equipment that facilitates each of the tests. In turn, to test the different manufactured models, we have 2, 3, 4, 6, 8 and 10” pipes according to ASME B36.10 with flanged joints according to ANSI B16.5 series 150lbs.
All equipment is tested before being shipped. The test is recorded and supplied, along with other documents, with the pumping equipment, these are:
✔️Certified exploded view: Cutaway view that indicates the parts of the equipment.
✔️ Dimensional plan: Necessary to plan the installation.
Each device has an assigned Serial Number, this is engraved on the pump plate. We have a complete traceability record so that, if the serial number is indicated when requesting replacement parts, the corresponding spare part will be known unequivocally.
We are pleased to share a new achievement in our company. The first gear pumps were manufactured. Argentine Industry destined for the Brazilian market, which will be installed in the plant next month. The quality of our products, combined with personalized technical advice and after-sales service, is opening new frontiers. This delivery marks the beginning of new relationships with the Brazilian and Mercosur industry.
Rotary gear pumps Drotec They are the preferred pumps for handling all types of viscous and clean fluids. Its reliability and durability have been demonstrated through many years of experience in all types of industries and applications.

The CA 150R equipment is part of our line of centrifugal pumps unassailable centrifuges.
The equipment has axial suction and tangential discharge and cantilever impeller that allow passage of large suspended solids. The impeller of these centrifugal pumps can be of the closed type or open type of swirl or vortex type. The greatly oversized bearings housed in a robust support are grease lubricated in the standard version and oil lubrication with a level indicator is optional. All CA series centrifugal pumps have vent and drain connections.
The videos show the equipment testing in our new test bench at the Berazategui Industrial Park plant.

The CAV 65-250 T equipment is part of our line of vertical centrifugal pumps.
These equipments have axial suction and tangential discharge and a cantilever impeller that allow the passage of large suspended solids. The impeller of these centrifugal pumps can be of the closed type or open of the swirl or vortex type. The widely oversized bearings housed in a robust support are grease lubricated in the standard version and oil lubrication with sight glass is optional.

Having finished in December 2022 the pCommissioning of our new industrial plant, we continue with our plans continuous improvement. With this objective, we are implementing a change in the construction material of our centrifugal pump bodies. sayings bodies which until now had been built in gray cast iron according to ASTM A48 CLASS 30, become of nodular gray cast iron according to ASTM A395 CLASS 60-40-18, which has many advantages.
In gray cast iron, carbon precipitates in the form of graphite. Its shape and size have a great influence on the mechanical properties of the casting.
The graphite appears in the form of sheets, this generates discontinuities in the metallic matrix acting as strong stress concentrators, resulting in a brittle material. for his part ductile iron precipitates graphite in a spheroidal form and is concentrated in volumes, which favors the elimination of discontinuities in the metallic matrix. This difference in the way graphite is precipitated between both materials, gives as a result that NODULAR cast iron is a material with greater ductility, high resistance to fatigue and better behavior at high operating temperatures.
Likewise, the nodular gray cast iron provides better machining conditions so the presence of graphite nodules act as a self-lubricant. This material presents a good behavior under vibratory stress since it allows them to be attenuated and presents a better performance in terms of fluid tightness, these motifs are of great interest to the application of this material in our centrifugal pump bodies.
Nodular iron allows to obtain mechanical properties similar to those of cast steel and superior to gray cast iron:
| Mechanical properties | tensile strength MPa | Elastic modulus MPa |
| Cast Iron ASTM A48 | 214 | 90-113 |
| Nodular Gray Cast Iron ASTM A395 | 414 | 120-132 |
Our centrifugal pump casings made of nodular gray cast iron are machined in our new HAAS VF4 machining center, which allows us to perform operations quickly, safely, accurately and with less cutting tool wear.
This change allows us increase the reliability of our centrifugal pumps, providing our customers with higher quality equipment without increasing their cost.
At Drotec we know that maintaining a Optimal stock of equipment and spare parts, it's a fundamental factor to provide our customers with quality service.
In this note, we show you our Current stock of ANSIMAG Magnetic Coupling pumping equipment and spare parts.
Since 1994, Drotec distributes in Argentina magnetically coupled centrifugal pumps brand Ansimag, part of the SUNDYNE group, without seals or gaskets, completely hermetic, free of losses and emissions.
Its innovative design allows pumping with great safety and under conditions of very heavy duty all kinds of corrosive liquids, among others, sulfuric, hydrochloric, hydrogen sulfide, nitric, phosphoric, chromic acids and sodium hydroxide, sodium hypochlorite, solvents, ferric chloride, hydrogen peroxide, etc.
The standard materials in contact with the liquid to be pumped are ETFE (Tefzel), FKM (Viton) and Silicon Carbide for bushings and shafts. This set of materials allows handling the vast majority of corrosive liquids. As an alternative, PFA is offered instead of ETFE and Teflon Gore-Tex instead of Viton.

We are ready to inaugurate the new Industrial Factory located in the Berazategui Industrial Complex. The project started in 2015 with the vision of a new Factory that allows us to fully develop our lines of equipment and accessories for the safe and reliable pumping of industrial fluids.
The new plant has 1600 m2 built between factory, workshops, dining rooms and changing rooms.
The plant has a new test pit, with control and report boards and sensors, to be able to test our equipment with maximum reliability.
We will be announcing the opening date shortly!
Thank you for being part of this great family.
