SPD 3-7.5HP IM 31 OCTOBER 2024 1.) INTRODUCTION The Novatec SPD vacuum pump is designed to be the next step in vacuum conveying. Traditional vacuum pump technologies, such as positive displacement (PD) & regenerative blowers (RB), are used to pneumatically convey plastic pellets or powders in a conveying system; creating a vacuum to “pull” air through the piping system.
SPD 3-7.5HP IM 31 OCTOBER 2024 More capabilities become unlocked when paired with Novatec’s FlexXpand Gen 3 (FX3) Central Conveying Control System: Automatic RPM adjustments based on one of four speed selections per loading station (Rabbit, Target, Turtle, Reducer) to accommodate different conveying distances, additive line sizes, materials, and velocities.

Seek Time is a control parameter that allows your pump to operate for short periods in vacuum break mode (no vacuum loading) while the system control searches for new demands.
SPD 3-7.5HP IM 31 OCTOBER 2024 7.) MECHANICAL INSTALLATION 7.1) General Installation: Only qualified technicians familiar with local and national codes should install this equipment. Vacuum lines should be installed as shown on the installation drawings. Clean compressed air (80 - 100psig) to be supplied to the air actuated valves as required (A filter, if not supplied, should be installed if the cleanliness of the air is questionable).
SPD 3-7.5HP IM 31 OCTOBER 2024 7.2) Combination Vacuum Breaker & Relief Valve The Novatec vacuum breaker valve for system seek operation also serves as the vacuum relief valve to regulate the pump’s workload. The dual functionality is accomplished by utilizing an equilibrium of compressed air pressure and vacuum level in conjunction with the vacuum breaker action, governed by the system’s control panel.
SPD 3-7.5HP IM 31 OCTOBER 2024 To maximize throughput, conveying lines that run the same material repeatedly will allow it to rest in the lines in-between load cycles. Line purging is another practice where the conveying lines are cleared in-between load cycles. This can simplify line cleanouts, minimize mixed material stagnation or separation from a blending source, prevent plugs at base of excessively tall vertical runs, and minimized moisture regain in dry-air or closed-loop conveying applications.
SPD 3-7.5HP IM 31 OCTOBER 2024 7.4.2) Vacuum Purge Take-Off (VPT) or Vacuum Purge Valve (VPV): Starts & stops material flow on-demand, regulating air/material mixture with material metering. Hard mount to dryer cone discharge, or inline after vacuum probe/lance • Consists of material inlet, outlet, and separate purge air inlet (either ambient or closed- •...
SPD 3-7.5HP IM 31 OCTOBER 2024 Figure 9: General Closed-Loop Conveying Schematic It is recommended, in this style system, to purge the conveying lines & store the minimum possible shot size of the dried material at the destination to avoid excessive heat loss & accumulation of any available moisture.
SPD 3-7.5HP IM 31 OCTOBER 2024 7.5.2) Discharge Selection Valve (DSV): Pump exhausts to atmosphere or can be pipe outside of pump room, for use in Closed Loop Conveying Systems. Consists of exhaust air inlet, closed-loop recirculation outlet, and ambient air outlet. •...
SPD 3-7.5HP IM 31 OCTOBER 2024 8.) ELECTRICAL INSTALLATION Connect the proper power supply (check nameplate) through a main line disconnect switch (not supplied) to terminal connections L1, L2, L3 and ground into the SPD control box that contains the motor starter.
SPD 3-7.5HP IM 31 OCTOBER 2024 Figure 14: PumpSense - General Monitoring 9.1) Base Package: Localized LED status indicators are available on the vacuum pump control box, to provide the pump status at a quick glance. Three indicators give color designated conditions of oil status, filters status, and overall pump health.

SPD 3-7.5HP IM 31 OCTOBER 2024 Oil & Filter indicators are primary maintenance items that have dedicated LEDs for status at a quick glance. The “Check Pump” indicator covers a multitude of other monitored parameters, and will provide the color status of the worst case condition.

SPD 3-7.5HP IM 31 OCTOBER 2024 13.) TROUBLESHOOTING 13.1) No Power or Won’t Start 13.1.1) Verify Incoming Power First, disconnect power at the main junction supplying power to the pump, verify all voltage leads are properly terminated at all components, including: disconnect switch, circuit breaker or fuse block, VFD, and motor terminals.
SPD 3-7.5HP IM 31 OCTOBER 2024 In some cases, interruptions in operational signals can occur at different sections of the circuit/system. Follow the incoming control signal wiring from the main controller to the pump terminal blocks: For general pump operation, check voltage per respective signals (24VDC): o Is there general power at the pump box input terminals: A (0VDC) &...

SPD 3-7.5HP IM 31 OCTOBER 2024 Rule of Thumb: On systems that convey material from one source to multiple receivers via a common material line; if only one receiver in the system conveys correctly, it is probably that receiver’s check valve that is not closing properly. 13.2.6) Conveying Pump Vacuum Breaker Valve Located on the central vacuum pump of the system, the vacuum breaker valve allows ambient air to be drawn into the pump when the conveying system is NOT conveying.
