This listing is for 1 of 2 Quattro Fluid SystemFlow 1000S

These units is in full working condition and is ready for immediate use

Overview & Application

The Quattroflow 1000 S is a quaternary (four‑piston) diaphragm positive‑displacement pump—engineered for gentle, sterile handling of shear‑sensitive fluids such as proteins, vaccines, cell suspensions, and other biopharmaceutical or food-grade products. Its design features—like seal‑less operation, low shear, low pulsation, and dry‑run capability—make it ideal for critical applications including:

Filtration systems: Tangential‑flow filtration (TFF), recirculation pumps, filter cartridges

Chromatography: Gradient mixing and feed pumps

Centrifuge feeding and homogenization

Aseptic filling lines and other sensitive processing tasks



Commonly processed media include albumin, IgG antibodies, enzymes, vaccines, cell and virus suspensions, dairy products, and cosmetic or polymeric solutions.

Technical Specifications

Here’s what’s known about its performance and build:

Flow rate: Continuously variable between ~25 to 1000 L/h (at atmospheric pressure); around 750 L/h at 6 bar (depending on configuration)

Max Pressure: Up to 6 bar, with high‑pressure variants available upon request

Drive mechanism: Four‑piston diaphragm setup actuated by an eccentric shaft; standard variant uses a 5° eccentric shaft reaching up to 1,800 rpm

Material & Construction:

Pump head: Stainless steel grades 1.4435 or 1.4539, optional alternatives (like PEEK) available

Membranes: Santoprene (diaphragm), EPDM (valve membranes)

Priming and Pumping Features:

Self‑priming, dry‑run capable

Four directional porting—pump orientation flexible

No shaft seals or wetted rotating parts, minimizing wear and product heating

Internal volume (filling volume): Approx 35 mL; designed to minimize dead volume and aid product recovery

Connections: Standard ¾″ TC (Tri‑Clamp) sanitary ferrule; other flange types available

Dimensions & Weight:

Pump: 523 × 155 × 212 mm, ~23 kg

Control unit (frequency inverter): 350 × 155 × 212 mm, ~6 kg

Electrical: 230 V AC (50 Hz) via a control box with 6.3 A fuse; motor IP54, control box IP53

Key Advantages

This model offers several standout benefits:

Gentle, high‑integrity fluid handling—ideal for fragile biologics due to low shear and pulsation

Contamination-free design—no mechanical seals, minimal abrasion

Robust operation—powerful 370 W motor, simplified maintenance with fewer parts

Aseptic and sterile process readiness—autoclavable, self‑draining, hygienic construction

Installation adaptability—four flow directions, small footprint, flexible hookups
