◆ Pump head options available: 6 rollers or 10 rollers. The 6-roller pump head has a slightly higher flow rate, while the 10-roller pump head exhibits lower pulsation.

◆ Expandable to up to 6 channels (6 tubes)

◆ 15-speed BCD DIP switch speed adjustment, or external signal speed control

◆ Switch quantity control for start/stop, switch quantity control for forward/reverse

◆ Speed Range: ≤100rpm

◆ Flow accuracy up to ±1%

◆ Panel or base mounting

◆ 24V DC power supply, AC power adapter optional for 220V AC power supply

Tube Installation

◆ Press the push button (DG-1A, DG-1B includes push button) or the corner of the card to remove the card

◆ Place the tube in the card slot; the two ends (STOP) will secure the tube to the card. The distance between the STOPS should be 72mm to ensure consistent flow rate across all channels.

◆ Insert the cards with the installed tubes into the pump body sequentially, completing the tube installation.

Control Circuit

◆ BCD coded switch, 15-speed adjustment
◆ When the BCD coded switch is set to "0", it is controlled by an external signal.
◆ Terminals 1 and 2 are external signal input terminals. Terminal 1 is positive, terminal 2 is negative. External signals include: 0-10KHz, 0-5V, 0-10V, 4-20mA, RS485 communication control, choose one.
◆ Terminals 3 and 5 control start/stop. Open or disconnected: pump runs; Closed: pump stops.
◆ Terminals 4 and 5 control direction. Open or disconnected: pump runs clockwise; Closed: pump runs counter-clockwise.
◆ Terminals 6 and 7 are power input terminals. Terminal 7 is positive, terminal 6 is negative. DC24V is recommended.
