ProMus Series
High Pressure Chemical Process Metering
The ProMinent® ProMus is a motor driven metering pump (Note: VFD control is not available for this pump) with a hydraulically actuated Teflon diaphragm. The plunger and diaphragm are hydraulically coupled and are precisely controlled by a mechanically actuated replenishment valve, which senses diaphragm position to admit coupling fluid as needed. The coupling fluid is continuously degassed to maintain accuracy. The drive case is protected from overload by a simple acting relief valve. The movement of the diaphragm depends on the amount of liquid displaced by the plunger.

Standard Lead Times for Products / Expediting
Standard lead times are listed below. If you need an order expedited, please contact your customer service representative. Please be aware that overnight shipments receive priority over ground shipments. Gala/Beta/Concept - 3 days Sigma series - 5 days ProMus - 2 weeks Dulcometer 3-4 days
When discharging to atmosphere, what steps will improve repeatability of dosing?
Installing a spring in the discharge valve of the pump gives some improvement, but for the maximum improvement, a backpressure valve should be installed at the end of the line.
Can I turn down a ProMus pump below 30% stroke length?
(YES) because the diaphragm is completely supported with hydraulic oil you can turn down the ProMus pump below 30%. There are some limitations though and it depends on the size of the pump and the pressure. Please contact ProMinent for Performance Graphs for each pump size.
Can I use a Variable speed motor for a ProMus pump?
(NO) because this pumps has internal mechanically actuated valving for the hydraulics and they are pressure dependent. We have found that when you use a variable speed motor it loses torque at lower RPMs. This can cause several problems such as: Not restarting after a stalled condition, Loss of flow or intermittent flow at lower RPMs, overheating of motors.
Can I pump High Viscosities or off gassing materials or combustible materials with the ProMus pump?
(NO)
Can I re-prime the hydraulic system myself in the field?
(YES) there are videos on U Tube of diaphragm replacement and Priming the hydraulic system.
Can I use the internal pressure relief to regulate process pressure?
(NO) there internal relief is designed to protect the pump and diaphragm only. Always use a external Back Pressure and pressure relief valve set below the internal pressure relief of the pump. If the pump runs in internal relief for longer than 24 Hrs. you need to must replace the diaphragm to prevent rupturing.
