Pump drives are ideal for all standard applications involving corrosive solvents or sterilized media

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 5101 pump drive 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.

Convenient large dials allow analog speed adjustment of DC motor. Pump drive features selectable rotation direction, overheat protection, an electrical current limiter, and a housing that allows stacking of up to three pump drives. Filling and emptying of tubing can be accelerated by the maximum speed push-button. Pump drives feature analog interface (0–10V or 4–20mA) for speed setting, direction of rotation, and start/stop function. Electronic speed control is accurate to ±0.5%. Flow rates are accurate to ±3.5%.
