CAT Pumps 2SFQ35SEEL.0110 Pump
Genuine Cat Pumps OEM — Cat Pumps Corporation, HQ Minneapolis, MN — supplied by ForeverPure Corporation, an authorized Cat Pumps distributor in Santa Clara, California.
The Cat Pumps 2SFQ35SEEL.0110 is a triplex plunger pump in the Cat Pumps 2SF direct drive plunger pump family, rated for 3.5 GPM at 100 PSI. Cat Pumps lists the 2SF as a compact direct drive plunger pump for continuous-duty service at moderate flow and high pressure — not a large-volume pump.
Typical Applications & Industries
Selected for this pump's actual duty — 3.5 GPM at up to 100 PSI, 316 Stainless Steel.
Common Applications
- Low-pressure transfer and circulation
- Filtration and cartridge-filter feed
- Coolant and process-fluid circulation
- Chemical, deionised and aggressive-water duty
Industries Served
- Water treatment and RO
- Chemical processing
- Food and beverage
- Agriculture, greenhouse and misting
- General industrial and OEM equipment
- Pharmaceutical and laboratory
Dimensions & Mechanical Data
Overall size, pump only: 6.8 x 8.7 x 5.2 in (173 x 221 x 133 mm) — dry weight 8.9 lbs (4 kg). A motorised unit adds the motor and mounting hardware; the shipping weight shown at checkout already allows for packaging.

Drive & mounting. 5/8 in electric hollow shaft with bolt mount, NEMA 56C.
Pressure regulation. SEEL and CEE models do not include an unloader, unlike the rest of the 2SF range. The system needs both a primary regulating device (regulator or unloader) and a secondary safety relief device.
Cat Pumps publishes the overall envelope and the mounting interface shown above, but no dimensioned outline drawing for the 2SF range. If you need a fully dimensioned drawing or a 3D model for a skid layout, ask us and we will request it from Cat Pumps. Figures from the 2SF Stainless Steel Data Sheet (2SF05SEEL_R).
Performance & Sizing
The 2SFQ35SEEL.0110 is a positive-displacement plunger pump, so it has no flow-versus-pressure curve in the sense a centrifugal pump does, and Cat Pumps does not publish one. Flow is set by the plunger displacement and the shaft speed and stays essentially constant as discharge pressure rises. Pressure is set by the restriction downstream — the nozzle, orifice or membrane array — and capped by the regulating device, not by the pump.
To drive the pump at a speed other than the rated 1725 rpm, or to size a motor, use the relations printed on the Cat Pumps data sheet:
| Flow at another speed | Desired GPM = Rated GPM × (Desired RPM ÷ Rated RPM) |
| Required horsepower | HP (electric brake) = GPM × PSI ÷ 1460 |
Maximum ratings apply individually — do not assume maximum flow and maximum pressure can be taken together. Talk to us before ordering if your duty sits near a limit.
