Garima Global has developed a wide range of AutoGRACE® brand pumps with leading manufacturers of oil pumps, water pumps, fuel pumps and hydraulic pumps in India.

AUTOMOTIVE OIL PUMPS

Engine Oil Pumps

An automotive oil pump, also known as lubricating oil pump, is responsible for circulating engine oil through the oil galleries built into the engine head and block with outlets at the sites where lubrication is necessary. Thus engine bearings, rocker shafts, camshafts journals, crankshaft journals, piston rings, valve stems and other rotating / sliding components of the engine are lubricated with a constant supply of engine oil pressurized by the oil pump.

Obviously any malfunction of the oil pump will directly lead to engine overheating in the mildest of cases, and complete engine seizure in the worst case.

Primarily engines are of wet or dry sump type – a single oil pump serves dual purposes of circulating oil as well as scavenging it from the sump in wet sump system, while in the dry sump case two different oil pumps carry out these two functions.

For standard applications unregulated pumps suffice the purpose of circulating the total oil volume 4-6 times through the engine per minute to achieve adequate lubrication.

However, modern engines use oil not only for lubrication but as a hydraulic fluid in small actuators like hydraulic tappets, timing belt tensioners and variators / VVT hubs in variable valve timing systems. This creates a disproportionately high demand for oil at lower engine speeds to power the various hydraulic actuators. For such cases AutoGRACE® brand variable flow oil pumps can adjust the delivery rate as per the demand of oil, independent of engine speed.

AUTOMOTIVE WATER PUMPS

Enigne Water Pumps

Majority of modern engines are liquid cooled, as opposed to the older air-cooled engines. To pump this coolant through the engine is the work of the engine water pump, or the coolant pump. Usually these are centrifugal pumps that circulate water (or coolant) through the various cooling channels cast into the head and the block. The coolant collects the heat and dissipates it through the radiator.

Water pumps are more susceptible to leakage issues than lubricating oil pumps since the liquid being pumped is much less viscous and can easily make its way through minute cracks or fitment gaps of the rotor seals. Quality of the seal is the single most important factor that determines the reliability of these pumps. A malfunction in the water pump leads to rapid increase in the operating temperature of the engine leading to expensive downtime of the machinery. If ignored, it will ultimately lead to engine seizure. AutoGRACE® brand water pumps are manufactured by the leading manufacturers of automotive water pumps in India, using only the best quality seals.

These pumps can be categorized into:

OPEN PUMPS

The pump is bolted directly onto the block and sealed using a flat gasket or sealing ring.

CLOSED PUMPS

These are self-contained assemblies and are mounted independent of the engine block.

DRIVE TYPE

Both closed and open type water pumps may be driven directly by the engine using gears, or by using plain or ribbed V-belts and timing belts of the engine.

IMPELLERS

The latest fluid dynamics models are used to design impellers that maximize pumping efficiency while considering manufacturing limitations. Impellers may be made of plastics, cast iron, steel, aluminum or brass.

Garima Global has also developed improved versions of OEM pumps by replacing plastic / fiber impellers with cast iron ones to make them more durable.

FUEL LIFT PUMPS & FEED PUMPS

Modern diesel engines apply two pumps to create sufficient fuel injection pressure at the injectors. First a low-pressure lift pump or feed pump is used to raise level of the fuel from the fuel tank up to the fuel injection pump. The high pressure injection pump then takes over and controls the quantity as well as pressure of the fuel inside the injectors.

Thus feed pumps play a complementary role in increasing the efficiency of the engine by assisting the main injection pump which is much more expensive to maintain and replace.

Garima Global sources its AutoGRACE® brand feed pumps from the most qualified and experienced manufacturers of feed pumps and lift pumps in India, so that our customers can be confident about their reliability and durability.

Automotive Lift Pumps And Fuel Pumps

HYDRAULIC PUMPS

Automotive Hydraulic Pumps

Although not strictly related to engine, in many applications like older models of tractors, the hydraulic pump is driven directly by the engine. It is used to pressurize the hydraulic fluid used to power various implements, attachments and tools attached to the tractor / construction machinery. Since they work under high pressure, reliability is fundamental to a good quality hydraulic pump, which is where Garima Global plays an integral part by sourcing them from the leading manufacturers of automotive hydraulic pumps in India.

PUMP REPAIR KITS

All pumps require maintenance at regular intervals, hence Garima Global has developed a comprehensive range of repairs kits for lubricating oil pumps, coolant / water pumps, lift / feed pumps and hydraulic pumps which consists of seals, gaskets, control valves, hydraulic chambers, control levers, hydraulic pump camshafts, Teflon® rings, hydraulic arms & shafts, safety valves, filters etc. manufactured by leading manufacturers of parts for hydraulic pumps in India.

FAQs

What are Automotive Engine Pumps?

Car engines rely on a team of hidden heroes: engine pumps. These pumps are like the circulatory system of the engine, constantly moving fluids to keep everything running smoothly and prevent overheating or breakdowns. There are different pumps for different jobs, but they all work together to ensure your engine performs at its best.

Types of Automotive Engine Pumps?

There are several types of automotive engine pumps:
  • Oil Pump: The oil pump is the engine's lifeblood mover. It constantly circulates oil throughout the engine, lubricating moving parts and reducing friction. This keeps your engine running smoothly and prevents wear and tear.
  • Water Pump: The water pump acts like a cooling system champ. It circulates coolant throughout the engine, absorbing heat and transferring it to the radiator, where it's released into the air. This prevents the engine from overheating.
  • Fuel Pump: The fuel pump is responsible for delivering fuel from the tank to the engine's injectors. It ensures a steady and controlled flow of fuel for optimal combustion and engine performance.
  • Hydraulic Pump: In some cars, you might find a hydraulic pump. This pump pressurizes fluid to power systems like the power steering or brakes, making them easier to use.

What are the key functions of automotive engine pumps?

The key functions of automotive engine pumps include circulating oil to lubricate moving parts, cooling the engine by circulating coolant (in the case of water pumps), delivering fuel under pressure to the engine (fuel pumps), and transferring hydraulic fluid to operate vehicle systems (hydraulic pumps).

How do automotive water pumps and oil pumps differ in their operation?

Both water pumps and oil pumps are crucial components in your car's engine, but they serve distinct purposes and operate differently. Here's a breakdown: Water Pump:
  • Function - Temperature regulation. The water pump circulates coolant throughout the engine block and cylinder head, absorbing heat generated by combustion. This hot coolant then travels to the radiator, where it's cooled by airflow and sent back to the engine.
  • Operation - Most water pumps are centrifugal pumps. They use a spinning impeller to create a force that pushes the coolant through the engine's cooling system.
Oil Pump:
  • Function- Lubrication. The oil pump continuously circulates oil throughout the engine's internal components. This oil acts as a slippery layer, reducing friction between moving parts and minimizing wear and tear.
  • Operation - Oil pumps come in various designs, including gear pumps and gerotor pumps. They utilize gears or rotors to create pressure and push oil through the engine's lubrication system.
In a nutshell:
  • Water Pump - Keeps the engine cool by circulating coolant.
  • Oil Pump - Keeps the engine running smoothly by circulating oil for lubrication.
  • These pumps work together to maintain optimal engine performance and lifespan. If you suspect an issue with either pump, it's important to get your car checked by a mechanic to prevent potential engine damage.

What materials are commonly used in manufacturing fuel pumps for automotive engines?

Fuel pumps for automotive engines are commonly made from materials such as stainless steel, aluminum, and composite plastics. These materials offer durability, corrosion resistance, and compatibility with various fuels, ensuring reliable performance and longevity in diverse operating conditions.

What are the signs that a feed pump needs to be replaced in an engine?

Signs that a feed pump (like a fuel pump) needs replacement:
  • Engine misfires
  • Loss of power
  • Difficulty starting
  • Unexplained surges in engine speed
  • Whining noises from the pump
  • Decreased fuel efficiency may indicate impending failure
Early detection and replacement of a failing feed pump is essential to avoid downstream engine damage.

How do I choose the right Hydraulic pump for my specific vehicle model?

Figuring out the right hydraulic pump for your car isn't easy, but here's the key:
  • Match Your Vehicle's Needs: The pump's pressure and flow rate (think water pressure and volume) need to match what your car's system is designed for. Check your manual for these specs.
  • Fluid Compatibility: Make sure the new pump works with the type of hydraulic fluid your car already uses.
  • Perfect Fit: The pump dimensions should fit the space in your car. Double-check the manual or consult a mechanic.
If you're feeling overwhelmed, refer to your car's manual or the manufacturer's website for recommendations. And don't hesitate to talk to a mechanic or hydraulics expert – they can be a lifesaver.

What is the typical lifespan of automotive engine water pumps and oil pumps?

The typical lifespan of automotive engine water pumps and oil pumps varies based on usage, maintenance, and quality of materials. Generally, water pumps may last between 60,000 to 100,000 miles, while oil pumps can endure the life of the engine if properly maintained. Regular inspections and timely replacements can extend their lifespan and prevent costly engine repairs.
