SP Single Piston Pumps
HPLC Pumps at Low Price, SP-22 and SP-21.

The Flom SP Series will be your great work force for both column maintenance and analytical purposes. The unique cam design minimized the total size of the pump and simplify the operation. The SP series provides basic function of HPLC pumps at low prices.
The difference between SP-21 and -22 is with or without pressure sensors. SP-22 has the sensor and -21 does not have the sensor. We offer PEEK or Stainless Steel pump head for both the SP-22 and -21.
