Peristaltic Hose Pump Tubing And Connection Fittings

Pump Tubing and Connection Fittings for peristaltic hose pumps are specially designed for long life and leakproof, trouble-free operation. Tubing connectors are color-coded for each tubing size to assure proper fit and secure, leak-free performance.

PVC Graduated Calibration Cylinders

Calibration Cylinders provide a simple means to verify the accuracy of the pump flow rate. Sigmamotor Calibration Cylinders are critical to accurate determination of your system flow rate, either at start-up or following maintenance.

PVC Mini Graduated Calibration Cylinders

PVC Mini Calibration Cylinders fit into tight locations and provide a simple means to verify the accuracy of the pump flow rate. USGPH (Gallons Per Hour) and ML are shown on the cylinder.

Glass Graduated Calibration Cylinders

Sigmamotor Glass Calibration Cylinders are made from Borosilicate glass. A rugged plastic outer shell helps protect the inner glass cylinder from damage. Process connection materials include PVC, Polypropylene, CPVC, PTFE, KYNAR, 316 SS, ALLOY 20 & Hastalloy C276.

Pressure Relief Valves

Sigmamotor pressure relief valves operate when the system pressure raises above the set pressure of the valve to protect systems from damage due to blockages or excessive pressure situations. The valve is set at 65psi at the factory but is easily field adjustable.

Back Pressure Valves

Sigmamotor back pressure valves prevent siphoning and varying rates of dosage from fluctuating downstream pressure by enacting positive discharge pressure in your metering pump system. The valves are set at 50psi but are easily adjusted in the field.

Pulsation Dampeners

SigmaMotor FL Series Pulsation Dampeners offer an inexpensive solution to protect chemical feed systems from harmful effects of pulsating flows. The simple chargeable design is CNC machined from PVC, CPVC, Polypropylene, PTFE or PVDF. The FL Series provides smooth, steady flows for better flow metering accuracy.

Pressure Gauge Isolators

Sigmamotor pressure gauge isolators allow standard pressure gauges to be used in corrosive services. The upper section (gauge side) is filled with glycerine. A diaphragm separates the glycerin from the lower section which connects to the pressure source. A 1/2″ FNPT port is provided for connection to the pressure source.

IQ Series Injection Quills

Sigmamotor IQ Series Injection Quills are used to provide safe delivery of chemicals into pipelines. The quill end ensures the dispersion of the chemicals away from the pipe wall. The integral spring loaded check valve prevents backflow from the pressurized pipe if there is a break in the discharge piping.

Visual Flow Indicator

The Sigmamotor Visual Flow Indicator allows for viewing of flow through a clear NSF61 approved PVC or glass flow tube. Caps are permanently fixed to the cylinder and include 1/2” FNPT, socket or flanged connections.

Check Valves

SIGMAMOTOR Check Valves provide reliable protection against back-flow of fluids in a chemical feed system. Check Valves are available in a wide variety of materials and sizes.

Foot Valves

SIGMAMOTOR Foot Valves are typically installed at the bottom of a tank to prevent fluid from flowing backwards out of a chemical feed system and back into the chemical storage tank.
