Hygienic supply pumps for pharmaceutical CIP skids

01

Tie the hydraulic selection to one identifiable wetted configuration

INOXPA describes PROLAC HCP as a close-coupled centrifugal assembly with casing, impeller, mechanical seal, cover, lantern and shaft, the latter coupled to the motor shaft by compression. Its product page distinguishes wetted AISI 316L from other steel parts and lists carbon/SiC with EPDM as the standard seal arrangement, alongside alternatives. [1]

For a CIP skid enquiry, identify the pump model, impeller diameter, operating speed and seal execution on the same selection sheet. List the intended cleaning and rinse steps, required flow and differential head at the pump, fluid properties and suction conditions. Ask the skid designer to identify the limiting circuit and the regulating method for the other circuits.

Keep the impeller and casing material records connected to the delivered parts list. Identify the shaft and any wetted shaft sleeve separately, since the drive shaft description alone leaves its contact with cleaning liquid unresolved. Record seal faces, elastomers and any flush or barrier connections on the ordered assembly drawing.

APV publishes performance curves separately from its W+ range overview. Request the curve for the offered size and speed, with the selected impeller and operating points marked; record the associated power and suction requirement. Preserve that selection with the pump identity and the skid operating range. [2]

02

Follow residual liquid through the installed casing, drain and valve

APV’s W+ pharmaceutical bulletin (07/2025) specifies a ½-inch clamp drain connection, excluding the valve. Allocate the valve and its installed drainage route in the skid scope. [3]

Review the actual mounting elevation and nozzle orientation on the skid drawing. Trace how liquid leaves the casing and connected pipework after the agreed sequence, where the drain discharges and how that connection is isolated during cleaning. Allocate responsibility for the valve, seals, support and controls between pump and skid suppliers.

INOXPA lists a casing drain port as an HCP option and limits its published 3-A configurations to specified connections, seal arrangements, elastomers and drain execution. Check the authorization or certificate against the ordered combination and its installation requirements. [1]

Ask for the maker’s instructions for cleaning, draining and servicing that configuration. During skid acceptance, observe the agreed drainage sequence in the installed orientation and record retained liquid or inaccessible low points for resolution. Keep this equipment inspection alongside the cleaning-cycle evidence managed by the pharmaceutical process owner.

03

Resolve the finish specification before assembling the handover file

APV’s pharmaceutical finish limits differ: below 0.5 µm Ra on the W+ webpage and below 0.38 µm Ra in its July 2025 bulletin, both electropolished. Reconcile the offered execution before setting acceptance. [2] [3]

Agree a controlled specification with the supplier: exact model and execution, required internal surfaces, finish criterion and inspection coverage. Match the measured report to that order and pump identity. A polished outside shroud offers a different inspection surface from the wetted casing and seal chamber.

The APV pharmaceutical bulletin lists EN 10204 3.1 records for wetted parts, a wetted-surface measurement report, order-referenced electropolishing/passivation certification and elastomer documentation. It restricts its EHEDG certification statement to selected models. Request the applicable package with the quotation, naming any exclusions or documents supplied by the skid integrator. [3]

At receipt, reconcile the nameplate, serial identity, material list, finish report, seal/elastomer designation and certified configuration. Record substitutions and their approval before installation. The pharmaceutical cleaning-cycle validation then uses the installed skid and its actual operating conditions; the pump’s material and finish file is one equipment input to that wider work.
