Pump drives are suitable for use with applications requiring the highest standards involving corrosive solvents or sterilized media

Pump drive features analog (0–10V or 4–20mA) and digital RS-232 interfaces for start/stop, selectable rotation direction, and speed selection. Pump DC motor features smooth stop, an electronic brake, overheat protection, and an electrical current limiter. Housing allows stacking of up to three pump drives. Filling and emptying of tubing can be accelerated by the maximum speed push-button. Electronic speed control is accurate to ±0.5%. Flow rate is accurate to ±1% on the PD 5201 and accurate to ±2% on the PD 5206.

The SP pump heads allow fast and convenient tube changes and feature ball bearings and rollers for tubing with 1.6mm or 2.5mm wall thickness. The SP quick heads feature a stainless steel five-roller system to reduce pulsation. They can also be used with the SP quick d pump heads on the PD 5001 pump drive to attach two pump heads to one drive. The SP standard pump heads have stainless steel and polyamide rollers with a convex shape to protect organic cell cultures. The SP vario pump heads can be used in a clockwise direction of rotation only and feature stainless steel and aluminum rollers with a convex shape for organic cell cultures and a removable rotor for cleaning.

The PD 5201 with multi-channel adaptor may be used in combination with multi-channel pump heads and cassettes. Choose multi-channel pump heads that accept either four small cassettes, eight medium or four large cassettes, or 12 small cassettes. The foot switch 82020-136 turns the pump drive on and off and is recommended for situations in which there is little or no access to the drive.

Flow rates for multi-channel pump heads and cassettes vary depending on pump drive and tubing size.

Microprocessor-controlled drive features calibration of flow rate and flow volume. The pump drives feature a four-digit display for speed, flow rate, interval dosing, and pause setting. Flow rates of the pump heads in combination with various tubing arrangements are saved in the program to enable direct digital readout of flow rate per minute. Saved dosing volumes are also selectable and interval dosing is possible by entering a time interval.
