Allweiler OptiFix Progressing Cavity Pump

Name: Allweiler OptiFix Progressing Cavity Pump – Brochure & Quote
Brand: Allweiler
SKU: ALLWEILER-OPTIFIX

Progressing cavity pump built for fast maintenance

The Allweiler OptiFix progressing cavity pump is designed for multiple pump series and for very fast disassembly and reassembly. The brochure claims up to 85 percent faster maintenance times compared with previous Allweiler designs, and a specially designed dismounting device that lets the stator and rotor be removed while the discharge casing and suction casing remain in the piping.

Breakthrough features named by the manufacturer include a patented zero play stub shaft connection and a high-quality joint construction. When the pump is fitted with an ALLDUR stator, pump life can be extended by up to 500 percent according to the brochure. OptiFix has a self-centering two-piece extension between stator and discharge casing, a double-sided inspection opening, a separate mechanical seal cover and a stator prepared for dry-running protection with the ATLS-T1V sensor.

Technical specifications

Data from the Allweiler OptiFix brochure (2018). Rotor and stator geometry define the two available series.

Parameter	Specification
AEB 2E-MF series	Sizes AEB 2E 200-MF, 2E 380-MF and 2E 750-MF; maximum pressure 10 bar
AEB 1F-MF series	Sizes AEB 1F 403-MF, 1F 553-MF, 1F 703-MF, 1F 1003-MF and 1F 1603-MF; maximum pressure 6 bar
2E geometry benefits	Low flow velocity and NPSH, gentle conveying of compacted products or large suspended solids, compact dimensions
1F geometry benefits	Volumetric efficiency, long service life, compact dimensions with high flow rates
Maintenance	Remove screws and extension piece, remove stator, remove inspection cover and rotor, loosen tensioning set, remove mechanical seal, drive-side joint and shaft
Dry-run protection	Stator prepared for ATLS-T1V sensor, no sensor contact with rotor or pumped fluid, no drilling or adjustment of the sensor sleeve
Spare part kits	Rotor with mounted joint; plug shaft with mounted joint
Fluids	Liquid to pasty consistencies, dilatant, solids-bearing, abrasive, shear-sensitive, adhesives, lubricating and non-lubricating
Industries named	Wastewater, pulp and paper, agriculture, environmental, industrial, ship building

Using the OptiFix in plant

The brochure shows the pump in wastewater and industrial sludge duty, where the stator and rotor are the wear parts. Because the stator and rotor can be removed while the casings stay in the pipe, the maintenance window shrinks and the pipework does not need to be disturbed. A common shaft and joint design across sizes simplifies spares holding.

Pick the 2E geometry for suspended solids and compacted products at up to 10 bar, and the 1F geometry for higher flow rates at up to 6 bar. The brochure does not list capacity or motor power, so request curves for the duty point.

Related pumps and checks

The Allweiler AEB-DE dosing pump uses the same progressing cavity principle for metering duty. Confirm fluid, solids content, temperature, pressure and elastomer compatibility before an RFQ. Other pumps are in the pump category, including the Allweiler TRILUB TRL V16-40R41 screw pump.

Documents and quotation

The OptiFix brochure can be downloaded on this page. Seven Star LLC is an independent supplier in Muscat; send fluid data, solids content and duty point in your RFQ. The brochure is a product overview, so curves and motor data come from the manufacturer on request.

Allweiler TRILUB screw pumps

TRILUB is Allweiler's name for a family of three-screw pumps built for lubricating and hydraulic oil service. One driven screw meshes with two idler screws inside a liner and moves the oil axially with little pulsation, which suits lube oil circuits of turbines, compressors, gearboxes and diesel engines. The listed TRL V16-40R41 is a complete pump from this family. Buyers who search for Allweiler oil pumps are usually looking for this kind of unit, in the GCC as elsewhere.

Ordering Allweiler pumps and parts: what we need

Send the full type designation and the serial or order number from the nameplate. For a complete pump add the oil grade and viscosity, flow, discharge pressure, speed and motor data. For parts, name the item needed, such as the screw set, liner, mechanical seal or bearing.
