Pump control - Uni or Bi polar stepper motor

Question

I am working on a robot that includes several annular gear pumps. We are using the MZR 2521,

manual: (please see section 5.5) http://www.micropump.com/support_documents/manual_mzr-xx21.pdf

product page: http://www.micropump.com/product_detail.aspx?ProductID=62

In the description they say that you can run the pump as if it were a stepper motor. This seems like it could be done perfectly with an Arduino, but I was not sure whether to treat it like a Unipolar or Bipolar stepper motor as the setup for each is quite different. Does anyone have any thoughts as to which it might be? Thanks so much.

Judging from fig.18 on p.22, this is a 4-wire bipolar stepper motor. Neat little pumps, by the way. — Nick Alexeev, May 21 '13 at 03:09
From reading the datasheet, it seems you have to choose which type of motor you order, and one of the options is a bipolar stepper (section 5.5). — Anindo Ghosh, May 21 '13 at 03:31
These pumps are the answer to a question I was just about to post. Thank you! — Qix - MONICA WAS MISTREATED, Apr 21 '15 at 02:44
