MMTV
VERTICAL PUMPS > MMTV
MMTV - Vertical Multi-Stage Pump with Barrel, using a high pressure vertical barrel
centrifugal pump often presents advantages and ensures trouble-free operation,
in those cases where the physical layout of the plant precludes the
installation of the receiver vessel at a sufficient height to ensure adequate
suction head for the pump under all operation conditions. This applies
particulary in the case of condensers in power stations. The barrel of the
pumps serves as a pit, and by adding the required length of rising main, the
pump can be installed at any depth desired.
APPLICATIONS
Pumping hot water and
condensate in power stations, especially in cases where the suction head is
restricted.
CONSTRUCTION
Vertical pump, single
or multi-stage, radially split suction, intermediate and discharge casing :
casing clamped together by tiebolts. The motor stool is flanged onto the
barrel, which is under suction pressure. The motor stool incorporates the
thrust bearing, the shaft seal, the coupling, and also supports the motor.

Description
The Torishima MMTV is a vertical mixed-flow multistage pump with canister, mainly applied as a condensate pump in power plants.
The high pressure vertical canister pump presents significant advantage inthose cases where limited suction head is available. This applies particularly in the case of condensers in power stations, desalination plants and other pipeline pumping applications. The canister serves as a suction receiver, and
by adding the length to the canister / pump, advantage suction head can be provided to ensure trouble-free operation.

This pump is vertical barrel type pump with
specially wide suction inlets and specially
designed vanes. It can be installed at low
positions. As a result, this type is most
suitable for use as a condensate pump at
thermal power stations, where sufficient
suction pressure is not difficult to achieve
because of construction requirements.
