PRODUCT RECORD

Recorded specifications and identification

This is a series, model or configuration reference. Family maximum values are independent catalogue limits and must not be combined as a guaranteed operating point. It is not a stock or delivery promise.

SELECTION AND SERVICE

Configuration and operating conditions

Cast-iron pump; seal and bearing options require fluid review.

Check abrasiveness and chemical compatibility first. Choose the connection size and speed from the duty curve, and include the required motor standard.

Independent family limits. They are not simultaneous operating points and do not establish the rating of an individual pump size.

• Use the pump serial number, complete designation and assembly drawing to identify the shaft seal or packing, rotor, idler, bushes, gaskets and relief-valve components.
• Send the required component positions and the existing material codes with your enquiry. Kit numbers are confirmed against the pump build; a WILDEN Air Kit or Wet Kit does not apply to this gear-pump design.

• Use the complete nameplate designation, serial number and component item number to confirm the equipment revision and fit.
• Check the fluid, temperature, viscosity, required flow, pressure, suction conditions and connection standard for the actual application.
• Confirm all wetted materials, seals, diaphragms and other selected components against the operating conditions. A material name alone does not establish suitability.
• For replacement parts, include photographs of the old part, its assembly position and relevant dimensions.
