5
Connection via pins to the motor or bearing housing
The simplest solution for maintenance.
It enables inverse rotation of the pump.
The splash ring protects the drive shaft against corrosion, further easing maintenance.
-
6
Various sealing systems available, including:
Single mechanical seal with and without quench, opposed double seal, and tandem seal.
The position of the seal is advanced for maximum transfer of the product flow. This improves the duration of the seal thanks to the greater convection that facilitates cooling. Product stagnation on the seal is avoided.
The quench and double seals should be driven by seal supply systems, suitable for the process, also API compliant upon request. It is also possible to install a vast range of seals according to standard ISO EN 12756 to meet every application need.

Variants
DM Series
The motor is directly coupled to the pump by means of a flange. This solution is extremely cost-effective and compact, significantly reducing installation costs and simplifying maintenance. The forces generated by the hydraulic part are supported by the motor. Each motor used has been suitably selected on the basis of restrictive technical parameters and subjected to numerous durability tests under heavy loads. The DM series is the reference point for almost all pumps installed in industry.
JM Series
The motor is connected to the pump input shaft via coupling. It is the best solution in terms of performance and durability. All the forces generated by the pump are absorbed by the bearings in the support. These bearings have a very high load resistance. They are mounted with extreme precision on components of the highest quality. It is the best solution when you want to ensure maximum durability and reliability, while requiring larger installation spaces. The bearing holder designed by us is modular and can be installed later in a pump with monoblock holder of the DM series. Represents the state of the art in this type of installation.
FM Series
The motor is directly coupled to the pump via the flange of the bearing support module. This solution is the most versatile as it allows the use of standard flanged gearboxes and output shaft, coupling with hydraulic or pneumatic motors, maintaining the simplicity and compactness of the classic monobloc solution while guaranteeing total reversibility and superior bearing support performance.
This bearing support module can be applied to the entire Diamond series and allows for quick maintenance of the motor drive. FM is therefore synonymous with modularity and reliability with any type of motor.
