The ODS is an air-operated diaphragm pump. Because it is a diaphragm pump, it is superior to centrifugal and helical screw pumps for heavy-duty performance. Because it is an air-operated diaphragm pump, it is significantly superior to mechanically or hydraulically operated models due to its simplicity of control and evenly distributed power transmission. The ODS® pump, is superior to other air-operated diaphragm models because it is designed and built for truly long-term, year-in-year out, heavy-duty performance. It weighs more – two or three times more than air-operated double diaphragm pumps...

How the ODS pump works The non-assist ODS pump the pump cavity. The pumping action is positive yet gentle so that delicate crystals and slurries can be transferred or metered without damage. SUCTION STROKE ADJUSTMENT NUTS ROD GUIDE SPRING SEAT COMPRESSION SPRING OPERATING ROD Fill stroke To fill the pump cavity, positive suction head (inlet pressure) is required. When inlet valve A is lifted by the pressure of the suction head, the slurry completely fills the pump cavity. The diaphragm returns to its normal convex position and the air exhausts. Discharge valve B, seated by line pressure, prevents...

ODS pump components and controls Variable timer Controls the operation of the solenoid valve to set the number of pumping cycles per minute and the length of the discharge portion of each cycle. The timer can be automated for paced control in response to a 4-20ma signal. The timer is housed in a protective fiberglass enclosure with a hinged cover, NEMA Type 4. Multiple pump operation options are available. Remote or linear response timers are also available. The variable timer is available in several designs. Timers are solid state electronic or PLC with a wide variety of timing ranges and options,...

Hinge assembly (Fig. 1) The hinge assembly increases the ease of maintenance when replacing or inspecting diaphragms. The assembly is also available as a retrofit kit for existing pumps. Pump Cover Discharge stroke position sensor A. Spring assist pumps (Model # 2S & 2BS) Fig. 2 (Model # 3E & 4E) Fig. 3 Current design provides a sensor located on the spring column tube which is activated by a magnetic disc in the spring assembly. Existing equipment can be refitted by mounting a proximity sensor to the spring column tube. The sensor is activated by entering the magnetic field. Pump Body Stroke...

Choose any of three check valves Type Q: Quick-opening ball-check valve This is the valve supplied unless another is specified. It is an all-around performer. A quick opening yoke permits easy cleanout and inspection without breaking piping. Positive seating of the ball is assured by gravity and guiding ribs. Ball and seat is replaceable. Type B: In-line ballcheck valve The valve is highly efficient hydraulically with flow passing vertically straight through. It is used in applications where maintenance is infrequent. Streamlined internal design reduces the potential for material to clog or hang...

How to install your ODS pump Location Locate pump to have as short as possible suction line. Allow ample space for inspection and maintenance. Air header Air pressure in pump should be set at 15 psi above the discharge head. Install air strainer/filter close to solenoid to protect air valve from loose pipe scale and other impurities. Install air pressure regulator and filter/ strainer in accessible location. Use air chamber(s) to dampen surges due to high inlet or outlet pressures to prevent water hammer. Noise Muffler on air exhaust will keep operation quiet. Foundation Use anchor bolts into...
