Pneu-Con SC1750PLVP-IB — Whisper Loader
Short headline: Pneu-Con Whisper Loader — SC1750PLVP-IB Proportioning Vacuum Loader with Vibra-Pulse & Interblend
________________________________________
Machine Overview & Summary
The Pneu-Con SC1750PLVP-IB Whisper Loader is a self-contained vacuum conveying system engineered for quiet, automated transfer and proportioning of dry bulk materials (pellets, regrind, powders, beans, grains). The PLVP model provides two-source proportioning (virgin + regrind) while the IB (Interblend) option introduces a static blending chamber to reduce layering and improve mix uniformity. The VP (Vibra-Pulse) option provides automatic filter cleaning for continuous performance. The unit is plug-and-play (120 VAC), shipped with pick-up lance(s), flexible hose and a NEMA 1 PLC control panel for timed proportioning and dump cycles.

Key Specifications (factory / standard features)
- Model: SC1750PLVP-IB Whisper Loader.
- Receiver Construction: Spun & welded aluminum vacuum receiver (stainless optional).
- Filter: DI-AC diaphragm-action flat disc filter (Poly-Felt, Nylon or Cartridge options depending on material). VP (Vibra-Pulse) auto-clean optional.
- Inlets: Dual inlets for proportioning (left = product 1 / right = product 2). Interblend (IB) divides receiver into compartments for static pre-mix.
- Dump Valve: 6″ gravity/flap dump valve with proximity switch high-level control.
- Vacuum Motor / Turbine: Brush-type motor with 2-stage turbine; standard 120 VAC single-phase (larger models may have 240 VAC option). Motor protection & overload circuit breaker included.
- Control: NEMA 1 control panel with PLC logic/timers for run (T1) and proportion (T1/T2), run/maintenance indicator lights, overload protection.
- Accessories included (typical): Pick-up lance(s) sized to inlet, ~10 ft flexible PVC hose (sized to inlet), hose clamps.
- Utilities: 120 VAC power (single-phase). Compressed air needed only if VP pulse cleaning installed (spec depends on VP kit).

What It Does (simple buyer-friendly explanation)
- Draws material from up to two sources using vacuum and deposits it into a receiving hopper or day-bin.
- Alternates suction between inlets according to PLC timer settings to proportion two materials automatically.
- Uses static Interblend chamber to pre-mix materials before discharge for a more uniform mixture.
- Keeps filters clean automatically with Vibra-Pulse pulses (if equipped) so the unit runs longer between maintenance cycles.

Core Functions & Capabilities
- Proportioning (PLVP): Programmable timed cycles for each ingredient (T1/T2) for controlled mixing ratios.
- Automatic Level Management: Dump valve + proximity switch prevents overfill — loader cycles on demand to maintain hopper level.
- Filtration Protection: DI-AC filter protects motor/turbine and reduces dust — VP cleans the filter each cycle to retain capacity.
- Gentle Handling Options: SOF (Spiral Open Flow) and wear-resistant inlets are available to protect delicate pellets/beans and reduce breakage.

Design Features & Benefits
- Aluminum body (lightweight, corrosion resistant) — quick install and lower weight for retrofits. Inpak Systems, Inc.
- NEMA 1 PLC with indicator lights — easy to program run/dump/proportion times and troubleshoot.
- Interblend (IB) static mixer — reduces material layering and improves mixture homogeneity before discharge.
- Vibra-Pulse filter cleaning — dramatically reduces filter clogging and downtime on dusty materials.
