Precision Sealless Pumps Pvt. Ltd.
Precision Sealless Pumps exports hermetically sealed Ammonia Pumps to the USA — EPA RMP and OSHA PSM compliant zero NH3 release design for US fertilizer plants (CF Industries, Mosaic, OCI Beaumont), Americold and Lineage Logistics cold storage refrigeration (IIAR 2 / ASHRAE 15 compatible), Gulf Coast petrochemical NH3 service and power plant SCR systems. ISO 9001 certified. CIF US Port.
Anhydrous ammonia is one of the most regulated chemical substances in the United States — listed under EPA's Risk Management Program (RMP, 40 CFR Part 68), OSHA's Process Safety Management standard (29 CFR 1910.119) and EPCRA Section 302 Extremely Hazardous Substance list. At US facilities storing or using ammonia above 10,000 pound threshold quantities — fertilizer plants, cold storage warehouses, food processors, petrochemical facilities — pump mechanical seal failures are the most frequently documented cause of accidental NH3 releases.
Our Ammonia Pump eliminates this release mode at the engineering design level: hermetically sealed with no mechanical shaft seal, no gland packing, no emission pathway. Under OSHA PSM, this is documented in the Process Hazard Analysis (PHA) as an inherent safety measure — removing the most common pump-related NH3 release scenario from the risk registry. Under EPA RMP, the sealed pump reduces the number of credible release scenarios that must be modelled in the Worst Case and Alternative Release scenario analyses.
As an ISO 9001:2015 certified exporter, we supply US ammonia pump users with a technically sound, EPA/OSHA/IIAR-compatible sealless solution with ASTM-referenced material certificates and SS316 wetted parts rated for anhydrous ammonia service. CIF Houston, Los Angeles or New York pricing in USD available with 22-28 day JNPT transit.
Under EPA RMP, US facilities must model worst-case and alternative NH3 release scenarios. Pump mechanical seal failure is a standard alternative release scenario in ammonia-handling RMP submissions. Our hermetically sealed design eliminates this scenario from the risk inventory — simplifying RMP documentation and potentially reducing the consequence zone radius used in the EPA RMP submission for the facility.
PSM-covered US ammonia facilities must conduct PHA/HAZOP identifying all credible release scenarios. Pump shaft seal failure appears in virtually every NH3 pump PHA as a release initiating event. Our sealless design removes this initiating event by design — documented in the PHA as inherent safety, the highest-level risk control in the OSHA PSM hierarchy, requiring no administrative or procedural safeguards to maintain protection.
US industrial ammonia refrigeration systems are governed by IIAR 2 and ASHRAE 15. Our Ammonia Pump is designed for continuous-duty anhydrous ammonia refrigerant (R-717) service — hermetically sealed design compatible with IIAR 2 equipment requirements for sealless liquid refrigerant pumps at Americold, Lineage Logistics and food processing refrigeration facilities.
US cold chain operators — Americold (world's largest cold storage REIT), Lineage Logistics, US Foods distribution centres, Sysco cold chain facilities — use large-scale industrial NH3 refrigeration. Our sealless Ammonia Pump eliminates seal failures that cause NH3 emergency releases, facility evacuations and OSHA recordable incidents in US cold storage machine rooms.
US fertilizer plants — CF Industries (world's largest NH3 producer), Mosaic, OCI Beaumont, Nutrien and Koch Fertilizer — continuously transfer large volumes of liquid anhydrous ammonia in synthesis, storage and loading operations. Sealless hermetically sealed pump technology meets the OSHA PSM mechanical integrity requirements for ammonia-handling equipment at these facilities.
US coal and gas power plants use selective catalytic reduction (SCR) systems with aqueous ammonia for NOx reduction under EPA Clean Air Act Title IV requirements. Our Ammonia Pump provides sealed, reliable aqueous ammonia transfer to SCR ammonia injection grids — zero NH3 atmospheric release at EPA-permitted US power generation facilities.
Purpose-built sealless NH3 pump for US fertilizer, cold storage refrigeration and petrochemical service — EPA RMP and OSHA PSM compliant. Dedicated ammonia pump technical catalogue with US regulatory compliance guidance available.
