Mechanical seal system SPA-526

A complete and fully functional Plan 52 system for arrangement 2 (2CW-CW) dual seals in accordance with API 682 or ISO 21049 latest edition – for shaft diameters ≤ 60mm.

For applications with a shaft diameter > 60mm, kindly refer to our SPA-528 units.

Our SPA-526 units serve the need for a more robust and all welded, yet flexible design that easily adopts to the more specific design requirements and/or high end client specs.

Standard configuration

Design ASME VIII, div. 1/not stamped and/or the European legislation (CE) such as PED 2014/68/EU and the ATEX 2014/34/EU – Zone 2 II/A T1-T3.

Wetted parts AISI 316(L) – Suitable for general oil/water service – Non-hazardous.

Design 40 barg @ -15/+90°C
ANSI 300# – NPS 6” – sch.40s.
Vmin 15 L @ NLL.

Seal supply and return connections ¾” NPT
All further connections ½” NPT
Coolwater connections OD ½”

Engineering units: SI units, Bar/°C.
NDE: Visual-/hydrostatic and leaktesting.
Surface preparation : Flopac std.

 

Available at request:

9

Designs tailored to meet your specific requirements.

9

High pressure designs (ANSI 600# / 1500#) for static designs up to 200 barg.

9
