Application selection
Pharmaceutical Paste Transfer Pump
A pharmaceutical paste transfer pump must be reviewed against the specific formulation and process requirement. Shubham’s LBX rotary lobe series is the starting technology for viscous or shear-sensitive paste. Final selection needs viscosity at operating temperature, flow, line pressure, suction, product-contact MOC, seal and the documented cleaning procedure. Compliance or cleanability cannot be assumed from the pump family alone.
Product behaviour
Define the supplied build against the process
A product name does not specify wetted material, finish, seal or cleaning evidence. Provide the plant’s actual material specification and cleaning method, including what must be documented at acceptance. The sales review can then identify which LBX configuration and records require confirmation rather than implying blanket regulatory compliance.
Keep validation requirements explicit
The LBX data supports a hygienic lobe-pump starting route, but it does not by itself establish that a quoted build satisfies a particular site validation protocol. Identify product and cleaning-media compatibility, leakage tolerance and documentation requirements before purchase.
Selection table
Paste process requirements for an engineering enquiry
Treat each requirement as a supplied-build decision, not an automatic series feature.
| Requirement | Plant data to provide | Review outcome |
|---|---|---|
| Formulation behaviour | Viscosity and shear tolerance at process temperature | Inlet filling, speed and product integrity |
| Wetted material | Approved MOC and product compatibility basis | Available pump-head and component configuration |
| Seal arrangement | Leakage tolerance, product and cleaning liquids | Seal and elastomer selection |
| Cleaning procedure | Method, chemicals, temperature and access need | Cleaning arrangement and documentation review |
| Process pressure | Line loss and receiving-equipment resistance | Pump and drive duty check |
| Quality records | Plant-required acceptance documents | Confirm what can be supplied with the quote |
System review
Trace paste from vessel to destination
A viscous paste can create different constraints at the vessel outlet, transfer pipe and receiving machine.
| Process point | Risk to describe | Information for sizing |
|---|---|---|
| Batch vessel | Poor feed at low level | Outlet geometry, tank level and inlet length |
| Transfer pipe | High pressure loss | Pipe bore, length, fittings and temperature |
| Receiving machine | Variable back pressure | Required flow and maximum discharge pressure |
| Cleaning changeover | Residual product | Approved procedure and inspection points |

Common questions
Pharmaceutical paste transfer questions
Does an LBX series name establish pharmaceutical compliance?
No. A specific supplied configuration and the plant’s required evidence must be reviewed. State material, seal, cleaning and documentation requirements in the enquiry.
Which material should be specified for a pharmaceutical paste?
Use the plant’s approved product-contact material requirement. The LBX data lists an AISI 316 pump head, rotors and shaft, but compatibility with the formulation and cleaning liquids still needs confirmation.
How should a paste cleaning requirement be stated?
Describe the actual procedure, cleaning liquids, temperatures, access and verification steps. Do not infer a particular cleaning capability from the word hygienic.
What duty data is needed when paste feeds a filling machine?
Provide viscosity at transfer temperature, requested flow, line dimensions, receiving back pressure, vessel outlet and minimum tank level so suction and discharge can be reviewed together.
