Life cycle cost explained
Energy dominates the LCC
Over a 5-year life, energy usually dwarfs the purchase price: a 5.59 kW pump running 16 h/day at ₹6.5/kWh costs about ₹2.12 lakh a year in power — over a lakh more than the pump itself, every year. That is why efficiency, not first price, decides the best buy, and why the energy-cost calculator feeds straight into this one.
LCC = CAPEX + energy + maintenance (+ repair + downtime where relevant). The calculator sums CAPEX, energy and maintenance over your period.
The repair-vs-replace module
The decision: repair the existing pump, or buy new. The module compares the extra cost of the new pump (new price − repair cost) against the annual energy saving it brings, and checks the payback against the repair life. If replacement pays back within the repaired pump’s expected life, replace; otherwise repair.
Example: repair ₹30,000, new ₹1.25 lakh, saving ₹72,600/yr → payback 1.3 yr, well inside a 5-yr repair life → replace. The numbers, not the habit, decide.
Honest estimates
Costs here are your inputs — use the overhaul estimator for realistic repair ranges and ask Teflow for a new-pump price on your exact duty. Energy savings of a new pump come from its higher efficiency: input kW = duty kW ÷ motor efficiency. Call +91 98251 62709 for a repair-vs-replace assessment with real numbers.
Technical & Operational FAQs
Q1.What is pump life cycle cost?
The total cost of owning a pump over a chosen period: purchase (CAPEX) plus energy, maintenance, repair and downtime costs. Energy usually dominates — often more than the pump price each year — which is why LCC, not first price, is the right basis for buying decisions.
Q2.How do I decide repair vs replace?
Compare the payback of replacing: (new pump cost − repair cost) ÷ annual energy saving. If the payback is shorter than the expected life of a repaired pump, replace; otherwise repair. The calculator runs this comparison with your numbers.
Q3.Why does energy cost so much more than the pump?
A 5.59 kW pump at 16 h/day, 365 days consumes about 32,600 kWh a year — over ₹2.1 lakh at ₹6.5/kWh. A typical chemical pump costs ₹1–2 lakh once. Over five years the energy bill is five to ten times the purchase price.
Q4.What maintenance cost should I use?
Realistic figures for chemical pumps: seal replacement every 1–2 years, bearings every 2–4 years, mag-drive rebuilds every 2–4 years. Use the overhaul estimator for range guidance, or your own plant records — consistency matters more than precision.
Q5.How do I estimate the energy saving of a new pump?
New-pump input power = duty hydraulic power ÷ (new efficiency × motor efficiency). Compare with your current input kW from the motor calculator or a clamp meter; the difference × running hours × tariff is the annual saving the repair-vs-replace module uses.
