Imo Pump
Imo - Model 3G Series -Three Screw Pump
FromImo Pump
Series 3G pumps are provided for differential pressures to 250 PSIG (17.2 Bar) and flow rates to 55 GPM (208 L/M). Mountings include foot or flange. Casing materials are either cast iron or steel. These three screw pumps are used for distillate fuel oil transfer and burner services, machinery lubrication and other industrial pumping applications. Most sizes are available with a tamper resistant built-in pressure relief valve for protection of the pump from momentary pressure overloads.

- Casing- Cast iron or cast steel.
- Rotors- Power rotor is ductile (nodular) iron. Idler rotors are gray iron. Rotors are nitride hardened for use in the 32-60 SSU (2-10 CST) range for fuel oils or for steel cased pumps.
- Shaft Seals- Type L: Steel backed Teflon double lip seal for cast iron pumps only, recommended for clean lubricating oil. Type V: Fluoroelastomer bellows mechanical seal with carbon on niresist faces, fluoroelastomer O-rings, recommended for viscosities below 3000 SSU (650 CST). Type H: Metal bellows balanced, positive drive mechanical seal with carbon on silicon carbide faces, fluoroelastomer O-rings, recommended for viscosities above 3000 SSU (650 CST) or for closer compliance with API.
- Bearing- Internal, ball type.
- Relief Valve- Optional internal, tamper resistant, built-in pressure relief valve for viscosities not exceeding 3000 SSU (650 CST). Specify differential set pressure in 15 PSI (1.03 BAR) increments, i.e. 45, 60, 75…255. This relief valve is intended for momentary protection for the pump against overpressure. It is not intended to be a pressure control device. Minimum set pressure is 45 PSID (3.1 BAR). Maximum set pressure is 255 PSID (17.6 BAR). Steel cased pumps can include an optional built-on, tamper resistant relief valve with external return to tank connection.
- Viscosity- 15,000 SSU (3200 CST) maximum except seal type V.
- Inlet Pressure- Type L seal 10 PSIG (0.7 BAR). Types V and H 50 PSIG
- (3.4 BAR) maximum
- Outlet Pressure- 250 PSIG (17 BAR) maximum [to 300 PSIG (20.7 BAR) with inlet at 50 PSIG (3.4 BAR)]
- Temperature- 0 to 225°F (-18 to 107°C)
- Drive/Rotation- Direct only. Clockwise rotation facing pump shaft standard. Counterclockwise rotation optional.
- Speed- 95 size: 5000 rpm maximum. Sizes 118-162: 4000 rpm maximum.
- Mounting- May be foot or flange mounted in any orientation. Vertical tank mounts available.
