IWAKI ERC-6210 24V DC HPLC Degasser Diaphragm Vacuum Pump

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. The IWAKI ERC-6210 is a 24 V DC diaphragm vacuum pump engine designed specifically for analytical HPLC degasser modules. It maintains strict negative pressure inside vacuum degasser chambers to prevent solvent outgassing, baseline drift, and pump cavitation.

Securing this unit as New Surplus delivers a total cost of ownership (TCO) advantage for laboratory inventory managers. Degasser faults automatically halt automated testing sequences. Stocking a genuine, factory-unaged IWAKI ERC-6210 eliminates long supplier lead times and avoids the high downtime risks associated with degraded second-hand units.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Turn off main power to the HPLC degasser chassis and disconnect the AC line cord.
2. Put on an ESD-grounded wrist strap to protect internal mainboards from static discharge.
3. Remove the top cover of the degasser module to access the internal vacuum chamber assembly.
4. Take reference photos of the existing ERC-6210 tubing routing and wire harness pinout.

Stage 2: Removal

1. Unclamp and disconnect the inlet and outlet vacuum hoses from the pump barb fittings.
2. Unplug the 2-pin DC power connector from the driver board header.
3. Unfasten the retaining screws securing the pump mounting plate to the chassis floor.
4. Lift the pump straight out, ensuring no strain is placed on adjacent vacuum pressure sensors.

Stage 3: Installation (Clone & Seat)

1. Verify that the new IWAKI ERC-6210 retains its factory rubber isolation feet to absorb motor vibration.
2. Align the pump assembly with the chassis base and tighten the mounting hardware snug.
3. Slide the vacuum tubes onto the barb ports according to your pre-removal photos and secure them with retaining clamps.

Stage 4: Power-On & Testing

1. Connect the 2-conductor wire harness to the mainboard 24 V DC header.
2. Power up the degasser chassis.
3. Measure the power rail to confirm a stable 24 V DC supply at 210 mA draw.
4. Monitor the status panel to verify the pump pulls down to operational vacuum pressure within 3–5 minutes and clears all front-panel warning lights.

Firmware/Software Versions & Upgrade Notes

• Hardware Independence: The IWAKI ERC-6210 is an electro-mechanical actuator powered by a 24 V DC rail. It does not carry internal flash memory or firmware.
• Cross-Platform Compatibility: The unit functions transparently across all mainboard firmware revisions of Agilent 1100/1200 G1322A, G1379B, and Shimadzu DGU-20A units.
• Control Interlocking Warning: Do not alter mainboard vacuum sensor calibration parameters during installation. Installing non-OEM alternative pumps with mismatched current profiles can trigger permanent error states on the HPLC system controller.

Frequently Asked Questions (FAQ)

Q: Is this IWAKI pump genuinely new, or is it a pulled and cleaned part?

A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.

Q: Why should we buy New Surplus instead of lower-cost refurbished pumps?

A: Refurbished diaphragm pumps frequently suffer from aged, micro-cracked internal elastomeric valves that degrade vacuum hold capabilities. A vacuum drop mid-sequence ruins solvent runs and causes costly sample loss. Buying New Surplus guarantees complete mechanical integrity and full service life.

Q: Is the IWAKI a direct fit for Agilent part number G1322-60000?

A: Yes. IWAKI manufactured the pump unit as the original internal component for Agilent G1322A and G1379B degassers, as well as Shimadzu DGU-20A modules. Dimensions, mounting plate holes, and electrical leads are identical.

Q: What is the expected service life of this pump under continuous duty?

A: Under standard operating conditions, a factory-new IWAKI provides an expected operational lifespan of 10,000 to 15,000 runtime hours. Service life is maximized when aggressive solvent vapor condensation inside the pump chamber is minimized.

Q: What documentation and warranty accompany this unit?

A: Each IWAKI includes our standard 1-year functional replacement warranty along with individual serial number tracking and physical inspection verification prior to shipment.
