Vector Model 4003 Peristaltic Pump

Lubricant-Filled Roller Design — 10 mm Hose, up to 39.6 GPH at 110 PSI

The Vector 4003 is a lubricant-filled roller pump for higher pressure and continuous-duty service compared with the similarly sized dry-case Model 2003. Fluid never contacts seals, valves or packing — the hose is the only wetted wear part. A food application that cannot use a glycerine/glycol-filled case is usually a better fit for the grease-lubricated 2003.

The performance curve separates continuous (24 hour), intermittent and occasional duty so the pump can be sized for 1,500–2,000 hours of hose life.

Technical Specifications

Fluid Handling Capability

• Viscosity up to 100,000 cps
• Liquid temperatures up to 180°F (82°C)
• Fiber length up to 2⅜″ (60 mm)
• Solids to approximately 1/16″

Hose Materials & Connections

The 4003 uses fiber-braided hoses in natural rubber, oil-rated NBR, EPDM and Hypalon. Typical hose life is 1,500–2,000 hours at 30 RPM. We can review chemical compatibility and provide samples for soak testing when needed. A searchable peristaltic hose chemical compatibility guide is also available.

Connections are ¾″ hose barbs in 316 stainless steel, polypropylene or PVDF.

Gear-Motor Options

Five ¾ HP three-phase 230–460 VAC TEFC gear-motor speeds are offered. Maximum pressure is speed-dependent:

Catalog maximum discharge pressure is 110 PSI. The two slowest drives are listed at 116 PSI on the order chart. Stay in the continuous-duty portion of the curve when the application runs around the clock.

Design Features

• Lubricant-filled cavity — constant hose lubrication
• Roller compression instead of a rigid shoe, for lower hose friction
• Self-priming; runs dry without damage
• Complete isolation of the pumped fluid
• No seals, cups or packing to leak or wear
• Reversible flow
• Low maintenance — hose change is the primary service item

Approximate assembled cost is $3,140 including the gear motor. Hose material and connection type can affect the cost. Final pricing is confirmed with the inquiry.
