Note: It is possible, for a special series of feedbox pumps, to link the propeller shaft
directly to an angular worm screw gearmotor, without any support.
4.4 Connecting rod joints
Depending on the type of pump, the connecting rod can use different types of joints (see
par. 9.3):
* Type SN1: Pin joint with elastomeric sleeve for smaller pumps.
* Type SN2: Universal joints with elastomeric sleeve and changeable bushing.
* Type SN3: Homokinetic joint with elastomeric sleeve.
* Type SN4: Pin joint with dual elastomeric sleeve and changeable bushing.
* Type SN5: Universal joint with elastomeric sleeve and changeable bushing for high
power.
* Type SN6: Universal joint with elastomeric sleeve and changeable bushing.
* Type SN7: Open Pin joint for use with foods without sleeve.
* Type SN8: Pin joint with short bell and flat sleeve.
* Type SN9: Pin joint with short bell for high power.
* Type SN10: Pin joint with short bell type “C”.
4.5 Sealing systems
The liquid sealing systems may change according to the type of fluid and to the
technologic conditions of pumping. The following types are available (see par. 9.4 and
Service manual):
* Type TEN 01: Packing seal.
* Type TEN 02: Fluxed packing seal.
* Type TEN 03: Oil seal.
* Type TEN 04: Single mechanical seal.
* Type TEN 05: Double fluxed mechanical seal.
* Type TEN 06: Mechanical seal for food application.
* Type TEN 07: Oil seal for worm gearmotors.
* Type TEN 08: Mechanical seal for food application with bearing.
* Type TEN 09: Mechanical seal with washing quench.
* Type TEN 10: Single mechanical seal (for pump type 010).
Note: Mechanical seals can be fluxed, or employ quench techniques.
On request, it is possible to manufacture mechanical seals complying with API 610
standards.
