Bridging the Gap Pumps Needed for Heavy Industrial

Applications Sigma’s Not Always Suitable Hydro and Makro Only Partial Solution Need Higher Pressure Orlita is too Large and Specialized Need for API 675 General Compliance


API 675 Key Points Removable Check Valves

• Spool pieces acceptable if proposed

Adjustable Over Turndown While Running Rated for 110% of Maximum Specified Flow Steady State Flow of 1% Over 10:1 Turndown Flow Repeatability of +/-3% Connection Sizes ½” Through 1-½” (Really!) Double Check Valves When Specified


API 675 Key Points Diaphragms

• Provisions to prevent excess flexure (Contour Plates?)• Double Diaphragms when spec’d

Internal Relief Valve Set at 10% or 25 psig Over Rated Pressure, Whichever is Higher

Packed Plunger Pumps Require Ext. PRV Stroke Adjustment – Manual or Auto

• Visual indication of Stroke Setting for both• Locking Device


API 675 Key Points Special Tools (upon request) Hydrotest to 1.5x MAWP (Maximum

Allowable Working Pressure) Repeatability and Linearity Test

• 100, 75, 50, 25, 10 Percent Up and Down (10 Point)

Data and Documentation Requirements


API 675 Specs You Don’t See Cast Iron Drive Case Stroke Speed Limitations Hydraulically Actuated Diaphragm Mechanically Actuated Diaphragm Restrictions on Lost Motion Control of Flow


Technical Specifications Hydraulically Actuated Diaphragm Pump Capable of 0.61 gph to 101 gph Capable of Pressures to 3500 psig Mechanical Lost Motion

• 10:1 Turndown Ratio on Stroke Nema 4 and Nema 7 Stroke Actuators Avail. Can Utilize Variable Speed Drives* Double Ball Check Options (17 & 30 Heads) Visual Indication of Relief Valve and Air

Bleed Valve Operation


Technical – ProMus Specifications Minimum Backpressure – 22 psig Maximum Suction Pressure – 50 psig Maximum Viscosity – 200 cps (500 cps w/ spring) Oil Quantity – 1.5 quarts Oil Type – Mobilube 1 SHC 70W-90 or equal Priming Lift – 5 ft Suction Lift – 7.5 ft Weight – approx. 50-72 lb w/o motor


Technical – ProMus Specifications Operating Temp. Range – 15 to 105 F Maximum Process Fluid Temp

• Continuous – 195 F• Intermittent – 250 F

Permissible Humidity – 95% Non-Condensing


Technical – Motors Need to Know Class, Division & Group

• Class – Gas, Vapor, Liquid or Dust• Division – When Combustible is Present• Group – Type of Combustible Material

Explosion Proof Motors• Class 1, Division 1• Class 1, Division 2 if Single Phase Power• Be aware of Group required for motor


Sales – ProMus vs mRoy Newer Pump Design

• Incorporates newer hydraulic refill technologies• Will not fail on starved suction conditions

Modular• Simple to modify in field

Easy to Hydraulically Prime Repairable Check Valves Very Price Competitive!!!!


Sales – Applications Chemical Plants

•Catalysts for Process•Additives for Plastics•Defoamers

Oil & Gas Refineries•Oil or Fuel Additives

Power Plants•Water Treatment•Boiler Feed

Boiler Feed Applications•O2 Scavengers•Anti-scalants•Amines•Phosphates•pH Control

LNG Plants•Odorant (Mercaptan)
