SSI High Pressure Pumps

Scientific Systems introduces a New Generation of very high performance, positive displacement pumps. State of the art engineering and advanced manufacturing technology have produced very affordable laboratory and small process instruments unmatched in performance and reliability.

M1 Series

Thomson offers the entire range of SSI high performance high pressure pumps positive displacement pumps. M1 pumps are compact, inexpensive, single piston, precise, positive displacement pumps with flows of 10 or 40ml/min at pressures up to 2,000psi. Fluid paths are either stainless steel or PEEK.

MX Series

MX pumps are economical, single piston and more pulse free with precision suitable for analytical and semi-prep HPLC. Flows of 10ml/min-5,000psi or 40ml/min-900psi are available. Fluid paths are stainless steel, PEEK or optional titanium.

LS Series

LS pumps are single piston pumps incorporating an advanced cam design for very low pulsation when combined with the micro-stepped motor and automatic pressure compensation. Their performance exceeds that of pumps costing much more. In addition to metering, they also can be use to dispense fluids. Flow rates are 5 or 10ml/min-6,000psi, 40ml/min-1,600psi. Fluid paths are stainless steel, PEEK or optional titanium.

LS Binary Series

Thomson offers the entire range of SSI high performance high pressure pumps positive displacement pumps. M1 pumps are compact, inexpensive, single piston, precise, positive displacement pumps with flows of 10 or 40ml/min at pressures up to 2,000psi. Fluid paths are either stainless steel or PEEK.

LD Series

LD Series are highly versatile dual-headed, pumps, delivering unmatched performance for analytical, semi-preparative, or flash chromatography. The patented, low dead-volume Pulse Dampener, advanced cam design and dual piston mechanism, provide virtually pulse-free operation. Automatic pressure compensation provides precise flows and very accurate gradients over a range of flows and pressures. Flow rates are 12 or 36ml/min-6,000psi, 24mL/min-10,000psi, and 100mL/min-1,000psi. Fluid paths are Stainless Steel, PEEK or optional titanium.

PR Series

PR Series are dual-head pumps, designed primarily for Prep and Semi-prep chromatography as well as many industrial and process applications. Flows of 100 and 300ml/min.

CP Series

CP pumps are unique, dual head, UHP pumps that provide constant pressure operation. Pressures to 25,000psi. Flows of 5ml/min-25,000psi, 12ml/min-10 or 18,000psi, 24ml/min-10,000psi, 100ml/min-5,000psi, 300ml/min-1,000psi.

LU Series

Please note, the 18,000psi – 5ml/min LU Series has been discontinued.
